<human>: We just broke up having both talked about it a few weeks ago.  We were both devastated but we couldn't think of a way around it because we live far away from each other and have very little money and it has become very repetitive with what we do so I find it quite boring.  

When I'm not with her I hardly think about her at all and sometimes used to think I would be happier single.  But now we've broken up it's like all the feelings I had for her at the start of the relationship have come back and I can't stop thinking about her.

Can you give me the gist of the text in a nutshell?
<bot>: I broke up with my girlfriend thinking I'd be fine but now I think about her all the time and I am very sad.
