They separated 2 years ago and I've been with him about a year. Not sure if it's relevant but she left him. I was not the ow, we met months after their split. They have one DC together and she has also moved on to a new relationship.
So onto the problem: I'm a little uncomfortable with their relationship as co parents. BF is a good father and on the one hand I really admire how they have managed to stay amicable. However, I feel like a lot of the time he bends over backwards to please her. He does a lot of swapping and changing of their contact arrangements at her request, usually so she can go to an event, or go out. I'm never consulted on this, even when it necessitates a change of our plans. There are other minor things which I won't go into but the overall feeling I get is that he panders to her somewhat whilst moaning to me about how 'demanding' she is.
On Mother's Day, she requested he buy her a particular brand of (IMO) expensive jewellery from their DC. As someone who doesn't wear jewellery, I don't really get it. I also get no presents at all from my ex on behalf of our DCs so it seemed very extravagant to me. However, I didn't let on my feelings as I felt it was none of my business. Then on his birthday, I know he was disappointed as she didn't get him the inexpensive item he'd requested but instead a few bits of tat that his DC confessed his ex had chosen.
It's her birthday next month and again she has requested an expensive piece of jewellery from the DC which my bf is to buy on their behalf. Bf has commented on this but I know he will still go along with her wishes and buy it.
I'm not sure if my own situation is clouding my feelings on this or whether I am right to feel a bit miffed about this. I suppose I'm just worried as we are talking about moving in together soon and ultimately these expensive gifts will then come out of family money. I worry that he will always put his ex's needs above ours as a blended family and it's leaving me feeling reticent to move to the next stage with my BF who would also like us at some point to have a DC of our own. However, I'm ready to be told I ABU and if so will keep my feelings to myself.
