Q: I have been seeing my best friends sister for about a year and a half as of a few days ago and he has no clue. The guilt eats away at me but i cant tell him. He will hate me and probably never talk to me again. It is his only sibling and if he knows we have both been lying to him shit will go astray. What do i do? I love her and we havent done much but we hang out and make out and do things like that. He cant know but i really love her. HELP.
