Hello,
My partner (both divorced, in 40s) spends a lot of time with his ex. He has teenage kids, and during a usual week the kids spill between the households, which often means so do the parents. She comes to his house and stays for dinner 'because its nice for the kids' or he goes to pick up one of the kids and she offers him dinner. Add on top all the texting (ostensibly about the kids) and things like they still do some holidays together etc.... it feels a lot. It has come to feel like I am simply providing the sex to an otherwise fully functional partnership. I don't feel nice and am on the verge of ending it, but I first wanted to check what's normal, in case I'm wrong. My ex is largely absent and so I don't have much of a co-parenting experience.
Thanks
