<human>: Hi.

Ex broke up with me two weeks ago and I've Been trying to move on. Though I've been getting these thoughts of murder or being really nasty to her. Though I then felt horrible for thinking such a thought, I wouldn't dream of doing to my enemy

I can understand why you sometimes hear about people killing their ex. Love is such a strong feeling - do you think they're just so butt hurt about the outcome that they can't accept it? 

I'm also thinking 'what if'. She said she felt bad for not picking up my calls and that she couldn't be in a committed relationship. I was only ringing/texting once or twice running up to the weekend to see if she wanted to go out on the weekend.

I thought things were going well together, when she said about breaking up it Completely caught me off guard. I had never felt so happy about myself or for a other person. I keep thinking it would've been nice if it lasted a bit longer ( I .e - see places together, have sex, chill out and watch films) though know that's just my own expectations of how I seen it?

Could you distill the essence of the text into 1-3 sentences?
<bot>: Ex broke up. Still thinking what I did wrong or if I could change it. Experienced bitter thoughts too  .
