<human>: I broke up with my girlfriend a few weeks ago. She loved me more than anyone else ever has and was completely heart broken when I gave her the bad news.

She rebounded quickly (within days) with someone who I know she does not love and it makes me really realize how great she was to me.

Essentially, I have began to question my decision. I still agree with the original reason why I broke it off, but vividly remembering how wonderful she was to me makes me think again. What makes me think even more is that I know that she still loves me, regardless of her recent rebound.

I do really miss her because we had a great relationship, but I don't know if I want her back because I want to back or if I am just lonely. This is also the first time I have broken off a very seriously relationship.

Can you give me a shortened version of the text?
<bot>: my ex-GF has rebounded and it has made me really want her back. I don't know what to think or how to feel about the situation.
