Mother issues

So we had my daughters 5th birthday party yesterday. I invited everyone. My mom and step dad wouldn’t come because my biological dad was going, my grandma (mothers mom & step dad), sister and brother were going to be there. She won’t talk to them. I get you don’t like them but they were fine with her coming and we’re just not going to talk to her. Keep their distance. Well I thought she could because she’s done it before and it’s for her grandkid. Well she wouldn’t come. So I offered just to do our own small thing. Just us and my mom and them. Well I got a text saying can we do it the 15th of this month and asked when they could pick her up. So basically I wasn’t invited. Even though I have to work, but they didn’t know that. Then instead it just being them they are throwing a whole party. Her other family (bio dad) will be there and she keeps forcing me to have a relationship with them when we only started talking to them 10 yrs ago and I tried and none of them seemed to care to try, so I quit. Plus they make it awkward when we do go over. So basically inviting people that weren’t going to be invited to her actual party. Would you be annoyed with this or say something? I mean I’ll let her go, but it seems like she doesn’t care what I think or want.
