I need some advice on my family on my moms adopted side. My mom was adopted. My mom and her husband (step-dad) and my grandma who adopted her and my uncle on that side who is not her real brother is all fighting over a lot of silly stuff. My sister told my uncle and his wife about Our mom didn’t get her or my brother anything for Christmas and my mom explains why Bc they had no money and my brother is 18 he just started vaping and they think my mom and husband gave it to him when he already had 2 weeks ago. Well I told my grandma that he is 18 now and not a little kid anymore. And on top of that my uncle and mom had some words out outside of my brother basketball game the week before one no what was said other than their sides. And my grandma was not there but is agreeing with my uncle. I told them I am not on no side that I am just mutual but I didn’t think it was wrong for them flock my mom all at once. So this Saturday my husband and I went to my brother basketball game and my grandma chased us after it was over asking us why won’t we talk to them and I told her I have to go get my daughter and she was apparently going to let it go so we talk about an hour telling her everything and that we need a break from everybody and she asked us well we see Lilly (my daughter) again. I told right now no she doesn’t need to be around arguing or fighting.

I am just tired of it they always judging others and I just don’t wanna to be a part of it. If my brother needs something yes I will help him or to come to his games yes I am there.

So what should I do? I don’t want my daughter keep from not seeing them like they did with me from my dad’s side.
