I(18F) met by tinder this guy(27M) with whom I ended up in a fake romantic relationship, fake because I didn't really love him but I cared ab him like a lot. His Ex killed herself 2 years ago and he has trauma about that. he told me that after her he didn't think that would ever love someone until he met me. But the thing is I'm not really sure whether he loves me or not truly because I think it is more like one of his unhealthy obsession to depend on and stay sane. during our relationship I slept with other guy but I don't even know am I cheater or not because I never really looked at it seriously. Now I'm breaking up with him after 2 weeks and feel shitty but still can't stay in a relationship in which I'm only for the other person not to end their life. Am I even doing right thing? Should I tell him that I slept with other?
