I know how you feel like. I really do. I'm not going to give you my story - because it's identical to yours - up the one word as to why he broke it off..."stress". I immediately recognized that you and I think remarkably similar.

I feel the EXACT same way you do. I agree, he SHOULD be taking responsibility - he committed to you, and he shouldn't just abandon. You respect his privacy and he should respect you enough to help you move on the way you do. He's not doing that.

That being said, there has to be acceptance in the fact that he just..won't be doing that for you. He just won't. I also wanted my boyfriend to help me move on and stay with me as I struggled to get over him, but he left as if he chopped MY hand instead of his hand in order to "move on with life". The pain was unbearable. He cut me off like I was nothing. Just nothing. Like I didn't exist, and if I did exist, it was like I was just this terrorist sucking his blood.

Your ex-boyfriend said the words, the sweet words, and he said the sweet words after the break up too. He most likely said it because he THOUGHT he would be okay with doing all that, but turns out he just doesn't care about you as much as he thought he did. This doesn't make him a BAD guy, but no matter what you try and do...you're not going to change his mind. He should be there for you, yes, but take comfort in knowing that you're not the only one.
I am one of those sad souls that moves on better when the person remains around me and I gradually move on, as opposed to just severing my hand off completely, leaving and then I attempt to live life with a wounded, bleeding stump of a wrist.

He's not going to come back. But take comfort in knowing you're not the only one. It's going to be years till you feel better. And I know what you mean by ending your life. I know exactly what you mean. I really do. A lot of people don't understand what you're doing through because it seems like people's heart have different material make-up. Some are made of steel, some are made of cotton, some are made up rubber (those hearts bounce back fast), and some are made of glass. These hearts are difficult to repair. People see them as so emotionally unstable, and I suppose it's true. They are. Glass shatters and can't be sewn or glued back together. Some hearts are resilient, some are more fragile. You will hurt for a long time, my friend. You will, and I want to tell you to hold on...but I think you will say there's nothing to hold on to. But you have to try. Because the ONLY other option is death, and I want you to live.
I agree with you on the false comfort. How people say, "there is someone better", "he didn't deserve you", and all those little words that people say to one another, but it isn't true. Sometimes...we really do miss out. Often...it IS our loss. But the reason people tell themselves that is so they don't end up feeling as broken hearted, alone and scared as you do right now. And I know where you are. I know.

The rest of the repliers did say something true though - he will only resent you more the more you keep contacting him. He doesn't want to be with you anymore, and even thought he promised - he promised he was there to stay...he's not going to. Even though he promised he was going to stick around after the break up...he's not going to.
He's not going to stay around. He's not.

I know it's hard to concentrate on anything else, and you don't really want to be around anyone else, and it's hard to not get mad at people easily as you're hurting, but my friend...don't contact him. He won't ever come back anyway - whether you do contact him or not. He's not coming back. This is going to be hard.

What I suggest...go away from where you are. If it's possible to relocate, or if it's possible to take a long trip to another continent. Somewhere cheap, India, Middle East, somewhere you like. Something that had NOTHING to do with him. I know your message is several months old, but I hope I hear from you. I want to know how you are doing. I want to know if you found a better source for relief. Because I need it too.
