<human>: We had been together for about 3 years. In the beginning of course everything was really nice, we went on lots of dates and he was super. Things progressed and we ended up getting a place together. We fought a lot at first but got used to living with each other. However we had some problems like incompatible lifestyles and aspirations, so we broke up. 

He was a jerk though and ended up in trouble with the law (and a hefty lawyer fine because of it), sexually assaulting me, driving drunk, dealing drugs to coworkers, dealing to his friends from our place, unknowingly buying date rape drugs because he thought they were workout supplements, ignoring me when he played video games (like not even acknowledging my existence when I would ask a question), seeming angry with me all the time (he always said that he wasn't angry but this was something his ex felt too. he would even get angry at me for being sad too much). He also got angry at me for not being "good enough" at my own aspirations.

Yet when he left for the last time I couldn't control myself crying and missing him already - it's so easy to think of the good times and the little kisses on my forehead and the hugs and experiences we shared. I don't regret the time we spent together but he is clearly a jerk so why do I feel so bad that he's actually gone now?? :( I feel like I'm crazy please let me know that I'm not the only person who has been through something like this.

Give me the gist of the text in a nutshell
<bot>: My jerk ex just moved out and I am crying and feeling shitty even though I rationally realize he's a jerk. How do I stop feeling bad?
