Finding out your ex has a new partner can bring up a lot of difficult feelings, especially when you already feel like time with your children is limited. It is a common worry among separated dads, and one worth addressing honestly.
Why This Feels So Hard
The concern is straightforward: someone else will be spending time with your children, someone who gets to be there on days when you are not. That can feel threatening, even if you know logically that it does not change who their father is.
Many dads describe a fear that their children might grow closer to this new person, or that they will eventually be replaced. These are natural and understandable feelings stemming from genuine love for your children and anxiety about your role in their lives.
If you are worried that your relationship with your children is being deliberately undermined, this is a separate issue. Organisations such as Families Need Fathers offer support and advice on parental alienation and can help you assess your situation.

The strength of your relationship with your children matters more than the presence of another adult in their lives. Children can and do maintain strong bonds with their fathers even when they see them less often than they would like.
When your relationship is secure, your children will not simply transfer their feelings to someone new. You are their dad. A stepfather or partner may become a positive presence in their lives, but this does not erase or diminish what you share with them.
If you feel your connection with your children needs work, the arrival of a new partner can heighten your concerns. In that case, focus on strengthening your own relationship with them rather than worrying about the other person. Regular contact, genuine interest in their lives, and reliability all help build trust over time.

Avoiding the Competition Mindset
It can be tempting to view this as a contest, keeping score of who does what or who the children seem to prefer. That mindset tends to make things worse. Comparing yourself to your ex's new partner, or trying to outdo them, puts pressure on everyone, including your children.
Children benefit when the adults around them can be civil and cooperative. You do not need to be friends with your ex's partner, but keeping interactions calm and respectful helps your children feel more settled.
What your children need from you is consistency and presence. They do not need you to be better than anyone else. They need you to be their dad.
Looking After Yourself
Give yourself time to adjust. For many people, these situations do not feel comfortable at first, and it can take months before the new arrangement starts to feel normal.
Talking to other dads who have been through similar experiences can help. Organisations like Families Need Fathers and Dads Unlimited provide resources and peer support for separated fathers across the UK, including online communities where you can share concerns without judgement.
If you are struggling with anxiety or low mood, speaking to your GP is a sensible step. They can discuss options including talking therapies available through the NHS.
Your feelings about this situation will likely shift as time passes. Everyone adjusts at their own pace, but what feels overwhelming now often becomes more manageable. Your children will show you, through their words and actions, that your place in their lives is secure.
After 2 months of separation, my son's ex partner moved her new boyfriend into her home.
This new boyfriend has 2 children but bizarrely doesn't see them. He also admits to being a Foster parent in the past but doesn't Foster anymore.
I could be worrying for nothing BUT......
What can I or my son do to ensure our 7 year old is safe with this man?
Anyway my ex has been bringing the same sleazy guy around our son. I dont want this guy around our son because there was an incident where he allowed his underage daughter into his bedroom with a guy she met on the Internet and she got raped, while he watched football downstairs, he then bullied her into not calling the police and verbally abused her, he left her the next morning to go to work and she tried to kill herself. Also a lot of other stuff like preying on vulnerable women on Facebook. Hanging around highschools offering rides home to underage girls, waiting outside nightclubs to give drunk vulnerable women lifts home. I've even been told by a few people to warn my ex to make sure he's not secretly videoing her and don't let him take pics as he's a habit of showing them to her mates.
Anyone any thoughts on what I can do.
He's made allegations that I'm a danger to the children and has even expressed his opinion that he wants to kill me.
He has even voiced this to the eldest child.
I don't condone his actions and tbh, I feel he's quite immature to be thinking this.
We have spoken to the police and have gone down the right channels.
Now whenever he picks the kids up or drops them off, I have to leave before hand so that he doesn't kick off.
He's stated before that he'll never be happy with the situation as long as I'm around.
Now my parter has found out she's pregnant and is stressed because she feels that once he finds out, my days would definitely be numbered.
There's no talking to him, and I feel as though my parter is taking the easy way to not cause any conflict.
I however, can't keep feeling pushed aside whenever he decides to want to see his kids.
Any suggestions?
My partner of 8 years & 3 children.
She broke it off suddenly..
The legistics of the housing situation ment we had to live together for a month.
I found out very quickly that she was in touch & meeting with a child friend, who I also knew.
It came to a head on our youngest 2nd birthday, I seen she was flirting with this guy over text while in the car with our children present. Very cheeky.
She moved out the next day..
Shes seeing him now & I've heard on the grapevine that he's just using her.
I've broke several times..
I've realised my family is what I make it.
It's hard ladies & gentleman.
Very hard.
Stay strong!
Exercise
Try & eat right
Make time for family & friend
Set short term goal
Set long term goals
My daughter got an award because shes been keeping upto date with her homework..
I did that sh*t.
She's hasn't even bothered.
Strength & control.
Unstick yourself.
Many thanks
On getting to this new town i felt lost and lonely being away from my work and being busy , it also opened a can of worms how my out of control my wifes drinking was and the toxic behavior that followed , i gave her an ultimatum its the drinking or or family she chose the drinking and i moved out back to home town 900 km away from the family , 1 year on she has a new partner who is living in our family home while i practically live on the street trying to get the house on the market so i can settle.
I am being very calm and not once ever text or called with any abuse which i think is serving me well at this point , what ever she throws at me i just let it deflect off me like i dont care , of course i do but need to be strong as possible.
Thanks everyone
