Most Helpful Guy
It hurts. Realize that he isn't coming back and take the time you need to yourself to move past him. It was a meaningful relationship to you and there's nothing wrong with that but it isn't in your future sadly.

Honestly, when you make people to center of your life, you run the possibility of being very disappointed. People are very fickle and anything can suddenly happen, much like how he suddenly broke up with you, said he wanted to try the friend thing, but suddenly turned around and said he didn't want even that anymore. I'm not saying you can't hold a person dear to your heart, but it shouldn't be at a point where you are left very vulnerable and your entire sense of happiness is only dependable upon that person.
Not that I mean to judge him, but I tend to think the whole "I need to find myself" speech is just another excuse for him to break up with you. If he needed to find himself or figure out who he is, I don't see why he went through the extremes to eliminate as much of you as possible out of his life as if you are disgusting in every way. My theory is that he probably found somebody else and needed you out of the way.
What tends to hurt in reading this is that it's very clear how he feels or has been feeling about you for a long time. Because for one, he said he didn't love you anymore. So, if that's the case, he had to have been felt that way for many days, perhaps weeks or a few months before the breakup, and just finally gathered the courage to tell you, Loving somebody is an intense emotion, and for that to suddenly disappear would take awhile. So, maybe he was thinking about breaking up for in advance. He doesn't even want your friendship. He decreased the chances of you getting in contact with him by blocking you. He is CLEAR in how he feels about you, yet you still tried to put your heart on the line for him by writing a letter to him. You really think he's going to care for that after everything he did to try to COMPLETELY exit you out of his life?
This has been somebody you dated for THREE years. You can't expect the pain to go away over night or in a few months. It will take a while to adjust in life without him. Learn from this experience, especially things like red flags you should have paid attention to, things you or he should have or should not have done, and signs on when to get out when a relationship is doomed. You still have a future way ahead of you and you are incredibly young to still have chances to meet all sorts of people.
He's simply not the one. Or, who knows; maybe he's gotta change into a better man for you LATER. You just never know.
