<human>: My boyfriend and I are doing quite well His previous relationship was actually very emotionally abusive and ugly. I helped him through it and later got him to get out of since we were really good friends and he would come to me for advise. We started dating a few months after the breakup. He has since cut all ties with her and has moved on very well.

But I still keep obsessing over everything she does. I used to keep tabs on her back when they were dating to check if she was cheating or not(she was) and I never stopped doing it. I check out where she goes, what she wears, how she talks, what she is interested in, heck if anyone has the slightest relation with her I stalk the shit out of them. One of the biggest issues if that since he used to tell me so much back when we were friends, the information about all the things they did together is still with me and I cannot stop thinking about it(like how she is perfect, which she isn't by far but I still remember him saying it). This is also partly due to the fact that I am insomniac and all these unnecessary things keep coming back at night.

I even make myself very upset sometimes and cause unnecessary problems with my bf, which is completely unfair on him. I ask him questions he doesn't want to answer because it brings up painful memories for him. I refuse to play games with him because I am not as good as her and don't talk to his friends because I am not as funny as her. Even though I know she is a shitty human being I still cannot stop being jealous of her.

But I don't know how to just let her go. I am ruining myself over it. Please I really need some advise here.

Can you give me the gist of the text in a nutshell?
<bot>: my bf used to confide in me about his ex before we dated and now I cannot get it out of my head and I stalk her way too much.
