<human>: Can you give me the gist of the text in a nutshell?

His last relationship was 7 years. She cheated and he left. He took a year away and dated casually during that time. Then we met and things went really quickly and intensely. He pushed for things to move quickly and then would back away. It made me get weird and eventually we started arguing. The arguing became unbearable and we agreed to take some time apart (just a week) when we met up after the week he said he needed to take things slowly and was afraid of the unhealthy fighting but wanted to make it work. He said he wasn't interested in anyone and wouldn't date anyone but wanted to start at square one. After a week he was distant but sweet and we hooked up like normal. Several days later he calls to say that he's too overwhelmed. That he cares but he doesn't think he feels like he should and he wants to end it.

I know it sounds insane because it was only seven months and I've only explained the worst part of it. I'll sum up the good by saying he was easily the sweetest most patient person I've ever met and he treated me wonderfully in all senses except his emotional baggage. 

Do I really just have to let this go? I feel sick to my stomach.
<bot>: My boyfriend is claiming he's emotionally hurt from his last relationship so he needs to end things. I"m freaking out...
