<human>: EDIT: My boyfriend broke up with me. Title is backwards.

The break up came completely out of left field. I genuinely thought we were doing great, we had plans to move in together in Jan. 

Then, without warning, I was dumped in the worst way possible. I was sent an email, with no real reason for breaking up, and then ignored. I have no idea what happened. And I've been such a mess.

I feel completely abandoned. I feel completely unloved and like I wasn't good enough. Despite doing all the things they say you're supposed to do (keeping busy, hit the gym, etc) I can't stop crying. Every time I have two seconds alone, I'm obsessing over what happened and in tears. 

Our relationship had it's normal annoyances and occasional argument, but we talked everyday, laughed often, and spent a lot of time together. There were no warning signs. I didn't know he was unhappy. Just a week prior to the break up he had brought up children and what he would name "our kids." I don't understand.

How do I beat this? It feels so terrible, I feel so alone. And I'm not feeling any better after a month.

Can you summarize the given text in a few sentences?
<bot>: BF of 2 years dumped me via email and disappeared. As far as I knew it was a great relationship. I'm devastated and need advice on how to move on.
