Dealing with parents.:?

So I’m a SAHM. Have been for almost 5 years. It’s typically just my husband and I raising our kids. Maybe once a month my mom or MIL will have them for an appointment 1-2 hrs max. We do make sure to see both parents for a bit at least every weekend or every other weekend.

We don’t associate with my family honestly outside of my parents and grandma. No one talks to me and I don’t feel the need to reach out to them. Recently my mom has reconnected with some of her family and suddenly has been getting super frustrated with me and my husband/making me feel guilty because I’ve turned down going to a football game and now she’s annoyed about a wedding… I haven’t seen my cousin in probably 2+ years. This was her response… I don’t even know what to say to this… I’ve always struggled with people pleasing and am trying to stand my ground lately. It’s frustrating to me that she feels the need to involve me and my family when NO ONE contacted me personally. Just like the football game. We had already made plans that day and she literally called that morning wanting us to drop everything and go to a football game to see my 2nd cousin play. We have 3 kids 4 and under and literally told her that wouldn’t even be enjoyable for the kids to sit and watch a game. She snapped and started crying and then hung up on me. This is the message she just sent me about the wedding today and I haven’t even replied yet… idk how to deal with shit like this and it’s honestly frustrating….
