Aw man, I’m sorry. This is exactly why I’m not out to my mother either. But the good thing is that our community has always been right there to offer support and fill that gap, when you’re able to get out on your own.

Would you like him to call you "Nancy Boy" in a nice way? That would be more disturbing than him snubbing you.

Every time he calls you "Nancy Boy", start singing it. It's a great song.

It will take time for him to fully process. I know several people it took over a year when their son came out. I am willing to say he still loves you but is trying to process it. He could be yelling and screaming about it, so take that as a good sign. Give him time and reassure him that you have not changed who you are. You are still his son and still love your parents. Let your mom help talk to him too. it sounds like you may have an ally there.

FYI, Nancy Boy is only derogatory,there is no nice way to use it
