so my mom, dad and i live with my 30 yo brother. he only pays the rent of his house, he has a wife and two kids. my mom is the main caregiver for my father and for her, her family has always been first. i also help my mother ALOT because no one else does. recently STUPID family problems mosly because of my brothers wife. there have been discussions. my brother told my other brothher the ssupposely " bad brother" that he cant come to visit his mother. he needs to take us out to dinner in order to see us. is that legal or something. again, my mother is the one who is taking care of my 76 yo dad, she doesnt get paid and never gets help from any other of my brothers and half brothers. she only gets help from the "bad brrother". i dont think this is about mom. i think this is mostly about my brothers haterness, because he doesnt even care if mom is sick or not. so why cant she see her son????? sorry if its too long and misspelled.
Yes, I suppose the one who pays the rent can say who can and can't come into the house. But how unfortunate! I don't know what the conflict is between the two brothers or whether banning the "bad brother" is justified (hard to believe it is), but all of this is very unfair to your parents and to you.
I hope some reconciliation occurs and things get back to more normal family relationships.
Meanwhile, can you and Mom and Dad visit "bad brother" at his house or apartment? Going out to eat sometimes sounds nice. Or just for ice cream. Visiting a zoo or botanical conservatory is another way you can get together.
Again, I hope the animosity will settle down. Perhaps you can talk to the brother you live with in a nonjudgmental non-accusatory way and ask him to be forgiving for Mom and Dad's sake. Until then, make sure the Mom has a way to see her other son often.
