How do I break up with my boyfriend??

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?

Hess not your boyfriend he is a request you sent and he said yes to. Delete him off your FB. You are not responsible for his actions or his threats of self harm You dont know him.

I believe you already have a post up regarding this situation ?

You cant have a boyfriend girlfriend situation with someone you have never met???? Have you too met in real life?

Breaking up with him ????? Simple solution delete him off your facebook .. problem solved !

Good luck with whatever you decide to do

If I have read this correctly you

Three days later, he's exuding behavior like this, I agree with Christina, delete him. If you've never met, you cannot even know these threats are serious and if they are, you can leave him a hotline message in a final farewell before Blocking Him.

Totally agree with you and Christiana,It's just that I don't think it would be as easy as that.The thing is his friends message me saying,"you'll be happy with him so don't break up or else XD"
that was one of them, if I were to unfriend him there would be this whole situation where his friends hunt me down and all. :/

Block him and be done with it. He is holding you emotionally hostage and you owe him nothing. I had a guy text me a pic of his revolver a few weeks ago. He wouldn't respond to me asking if he was ok for over 2 days. In those few days I didn't sleep and had horrible nightmares. I sent him one last goodbye text and blocked him everywhere. Knowing him, he probably thinks I'll come back at some point.

Have you ever heard about Boundaries ? They are used to keep your life in good shape ... Not allowing people to talk you into things you don't want to do etc..

When your friends say " oh you would be happy with him" .. Your response should be I am not interested in him he was only someone I added to my facebook , Thank you for your comments and opinion but I am just not interested at all " Simple solution .

This is a good way to learn how to handle people you meet online or real life... Look into learning boundaries and how to use them ..its something you will be using all your life ..

Be safe who you allow onto your Facebook and it something feels wonky just delete them..

If his friends "hunt" you down just delete them also .. If they actually know you in real life .. call the police and get a restraining order ..

Keep in mine YOU have control over Facebook and all the drama that comes with it .. Maybe you need to review your list of "friends" and delete and block ones that are a problem.

Stay safe
