<human>: Can you succinctly summarize the text in 1-3 sentences?

The breakup itself was not bad, there were strong emotions and sadness which is normal but no hate (or so I thought) anyways for some weird reason we kept talking as if nothing had happened except that it was a friends. About two or three days later she sends me a big text message saying we shouldn't talk because I broke her heart and such and I was happy to oblige because I felt weird doing that. I thought I had gotten over her but now when I find a remnant of our relationship in my cellphone or laptop or whatever for some reason I get angry not to her not to myself just angry and I don't know why. 

PD found out she wanted revenge on me for breaking up with her but since I moved out of town she couldn't but I don't get it like after we broke up people started telling me stuff and I even got to see her like that that just wasn't the girl I knew even before we were together, I guess she took it very badly and sometimes I feel bad about it as if I caused it...
<bot>: sometimes I get angry for no reason when I find ex-relationship stuff and feel guilty sometimes about breakup "fallout"
