Let me explain everything.

My boyfriend of over 2 years and I have talked about marriage and he asked me about my preference for a ring and blah blah.

Recently (for 4 months now..) he's been extremely insecure to the point that it's hurting our relationship. He constantly tells me that I don't love him or care for him if I don't do something or if I don't reply right away. He doesn't understand I can get busy within the minute and can't reply.

I'm not a very emotional person and it frustrates me so much. I don't like to talk about feelings or show my emotions at all. He plays games and whenever he's like "ok don't talk to me", I don't fucking talk to him. Then he gets mad because I didn't call or text him.

I'm so fed up with being forced to say how I feel 24/7, and it's not a simple "I love you". It has to be a paragraph of why I love him or why I care.

He's super needy and I can't anymore. I am done. I love him but this is too much. I have no idea what he would do if we were to break up. All of this is too much for me.

How do I break up with him without him putting the blame on me or threatening to kill himself?
