I have an opportunity to tell my mom that I am gay every day for the next three days and I only realized it minutes ago, should I tell her??? She can't flip out and there is a 98% probability that she will accept me and not reject me or something, because she is in a very very good overall attitude to everything and we are alone quite many times a day and I wanna tell her so should I?? I almost did but I decided to ask for advice before instead of help later...
Well, a 98% possibility of acceptance sounds pretty good to me! The question is, are you ready to come out? Are you secure in your identity, ready to answer questions concerning your sexuality? If so, then I'd totally go for it. Good luck!
Yup, as DreamerBoy said, as long as you're comfortable and confident in your sexuality, and you're confident that she'll be supportive, go for it! You'll feel SO much better!
