Welcome
@Gammareen !
I am sorry to hear that, wish it were different for you. I am sure you can find some folks here who will commiserate with you, and maybe even offer useful advice.
My closest experience was with my brother and his family.
That brother never has been very friendly or talkative, his wife less so. My parents were divorced so things were different for each. My father got mad and complained that he did not get the respect he should have from them. Result is he had little contact with them.
My mother on the other hand worked at it pretty hard. She never got invited to their house so she would just go, get a motel, and call to tell them she wanted the grandkids for planned activities. Sometimes it worked, sometimes not and she went home without seeing them. I know she was hurt, but she never showed it or complained and slowly she did build relationships with her grandkids and with time a bit with my brother and his wife. Not ideal, but a whole lot better than with my father.
Not suggesting this would work for you, it might but only you know your situation. Just what I can think of that might be helpful.
