I just need to write things down so my thoughts are in words to help myself understand it better.
Will the insecure feeling of my partner and his ex (BM) being around each other ever go away? It's the history that comes with it all, I think. She's not a horrible person and we get along fine but it's just weird. I feel like a third wheel. Nothing that he is doing, it's just how I feel.
His family still invites her to events, where do I fit into this? I'm supposed to be part of the family now but I just feel like a tag along. I don't want to go to things with her being there. I get that they are all still friends, they still consider her as family though so how can I be family too? There can't be two people taking the same role essentially. As an example, his nephew will still see her as his auntie, fair enough but again, it just confirms how I don't fit in anywhere.
When the kids have a birthday party, it's been a joint arrangement for his and her families to go to. This was prior to me meeting her so at that point, it would have been awkward but even now, it still would be. I'd feel like just a random person going to two already established joint families. I can't expect my partner to not go to his own kids birthday parties though and wouldn't even ask that of him.
And then where does my family fit into this? I don't have kids of my own, I'm trying to create a new life with my partner and his kids and my family being involved with that too but how would that work?
I love my partner more than anything but I'm really struggling to see and work out how this all will actually work.
