Would you be annoyed if you'd been with your dp a while and suddenly he started to spend more time with his ex on the days he has the children ? It seems like every other weekend they play happy families going off to places or out for dinners .. He even took her with them to visit his grandparents.
It's not always been like this but the last few months it has crept up.
I've asked him why he feels the need too suddenly. ( if it had been something they'd always done since the split I think I would be slightly more according but they haven't and it's only the last few months it's changed). I thought he might have said he felt the need to because she's their mother but instead he said it wasn't out of duty, that he enjoyed catching up with her and hearing about her job and life.
As far as I'm aware there is no contact between visits unless dc related I just don't understand why she needs to be there and why so regularly.
