Most Helpful Guy
First, let me say that you sound like a wonderful girl, so it is his loss. However, bear in mind that many guys won't give a girl closure like that, or even talk to them after a break up, so count your blessings that at least you have some answers, even if they didn't lead to a more friendly outcome. Still, this is the more common outcome with many guys, as most do not want to be friends, or even speak to the girl again. Also, in this case, it sounds like the relationship must have been very frustrating for him in the end, and it left too many bad memories. Memories he would rather leave in the past and forgotten. But again, at least he was straight with you to a degree. I'm not saying this is how I would handle it, but in a way I can understand why he behaved that way. Either way, you can't get caught up on the whys and what-fors, wondering why you were blocked. That will lead nowhere, but to confusion. And in the end, who cares? It is done, over, and there is nothing you can do but acknowledge it. Hopefully you learned something from it, and can move forward into a new day filled with positivity and new possibilities, knowing better what you want and need in a relationship next time.

He blocked you because he has decided that he wants you to be his past so in order to commit to that choice, he must follow suit by not making you his present or future. I can't say for sure why he kept his other exes as friends as opposed to you without knowing more about the dynamic of the relationships. It may be because his other exes have legitimate mutual friendships with him or they are in his same friendship circles. Or it could be because for whatever reason, he plans on getting back together with them in the future or even just fucking them/pursuing a depthless, meaningless f*ck buddy relationship with them.
