My SIL used to be my best friend. She left her husband and came out of the closet and slowly pushed me away. I fully supported her and invited her new girlfriend to everything I had at my house and still it seems her new girlfriend didn't want me around anymore. I just don't know what else I can do to support her or be there when I am being pushed away by her new love. She still text me and stuff but it seems to be when her girlfriend isn't around. She missed most of my son's life because of it and my entire pregnancy so far with my second one.
Re: Hi....question if you wouldn't mind.
Well my first reaction is that this has nothing to do with being gay. I've seen the same thing happen in plenty of straight relationships. Often when people are in new relationships that other person becomes their world (good or bad). Have you talked to your SIL about it? Have you clearly told her you miss her and want her in your life more? Have you told her that you want to get to know the gf as well and hopes that gf will get to know you?
I've been in situations like this and I think sometimes we have to remember to go back to communication 101.
Good luck!
