Technically I wouldn't call him my boyfriend because I don't love him at all.It was about 3 days ago(I'll call him Alex) :/ I guess I just sent a request to him becase he was cute.Turned out he accepted it,straight after he ended up asking me out and before I was able to answer he showed my a picture of his arm(self-harm)
I guess I just thought that you know this guy needs help seriously,so I'm going to help him.So I said yes,since then we've been dating.
And everyday he's been asking for sex and telling me he loves me...o_O like seriously.
Yesterday I tried breaking up with him through fb.I brought up the fact that we don't suit.And suddenly he said how he would kill himself if we break up,and that he loves me so much and wants to love me forever also that he wants us to be happy together even if it means no sex.
I still don't like him even when he said that,later he even sent me a "18+" photo.
I've decided that me just disappearing from his life will be easier for him,if only there was a way to break up with him without him knowing and saying how he'll commit suicide,I really don't want to hurt him in any way.

I need to break up with this guy and don't know how...help?
