Well, in that case, that if they truly don't like you because you are gay, and only try to insult and hurt you, then I would cut them off. Loosing the useless heavy baggage - no matter how blood related or how accustomed to them you may have grown - might be the way to go. Don't know the full situation here, so this is just some thing for your own consideration, some thing to which to mirror your own bonderings.
And I don't know how long have they known that you are gay, cause some times people need time to realize that the person who has come out, is still that same person. Don't do anything hasty, don't make decisions this big when angry.
I have had to cut off few relatives for other reasons, but they wanted only bad things for me and detested me. I have never regretted the desicion I made, and had almost forgotten them all together. Nobody needs people like them in their lives, and I let people like that know that:butslap: When I end things, I want it all to be clear to everyone why it has happened, so nothing leaves open, to linger in ones thoughts. After the fact that I know, that they know, it really doesn't matter anymore what they think.
