My Roomate is one of my good friends I have known her for 6 years, she was my ex fiancés best friend before she met me. I am 24 dating an 18 yo guy, I am not out but getting close to coming out. She knows my family as well, I want to tell her I am dating my boyfriend Ryan, but I know she has a problem with older people dating 18 year olds, and I don't want her blabbing her mouth to my ex fiancé who also has a big mouth. She just asked if I'm seeing someone, I avoided the question and she text me basically saying it's obvious I'm seeing someone and why won't I talk to her about it. WHAT SHOULD I DO?
