<human>: Ok, I broke up with my girlfriend a few days ago because I have trust issues with her.  Then, 2 days after, I realize that I had made the biggest mistake of my life so far.  I know that's odd of me to say since I'm 16, but it feels like it.  All I want is to be with her, but all I seem to do is make everything worse.  I get mad easily and I don't think before I speak.  I'm ruining our friendship and any chances of me getting her back.  Shes told me that she's already moved on (we broke up 4 days ago) and that just hits me hard and makes me sad.  I just want to be with her again.

Could you distill the essence of the text into 1-3 sentences?
<bot>: Want to get my ex back after I broke up with her 4 days ago, but I make an ass out of myself.
