H and I split end of last year. It was my decision to end the relationship but my hand was forced by his attitude to money, the way he treated me and the children, and the final straw was finding that he was talking to other women on dating apps.
He moved on very quickly and has been with new girlfriend for 5 months now. I have found this very difficult to deal with. The children haven’t yet met her, but I’m sure it’s going to happen soon from what he’s been saying, as they are talking about all taking holidays together in the autumn.
We are mostly amicable even though he can be a little unreliable about contact and maintenance. My problem is I am dreading the next stage of him becoming a “blended family” and her meeting our kids and them all spending time together (she also has kids). But, I realise that it’s inevitable that this will happen and I have no intention of preventing it (not that I could).
I just don’t know how to put my feelings aside and move forward in a positive way, this will clearly change the dynamic of everything and I guess I’m just asking how I can navigate it all. I don’t want to be the horrible ex, I don’t want the kids to be sidelined either. They are 6 and 3, so we have some years of co parenting to go yet. This is completely new territory to me, how do I navigate it?
