Me and my girlfriend are essentially best friends, and according to her (something that I believe), I'm one of, if not the only source of happiness in her life. A few weeks ago I had the realization that I am gay and I've been stressing immensely recently because I know I can't be in this relationship as a romantic partner. I don't know how I would do it, and I don't even know if I should. I'm scared of losing her as a friend and I don't know if I can go through with breaking up with her. We have mutual friends and I don't want them to turn away from either of us, because over the past year we've all built a great support system and I don't want to ruin that. I'm so scared that coming out would just cause more pain than happiness at this point, and that it'd just be greedy. Am I wrong for thinking the way that I am? Is it wrong to potentially ruin multiple great friendships just for myself? Would I be the asshole if I came out to my girlfriend, and potentially ruined her time at college?
