<human>: Ex bf - 25. Me (girl) - 21

Just a little background story. We have been together for 3years and a month when he broke up with me last Christmas. I was devastated because I really loved him. I admit I was a bitch to him (ie I get mad at him for the slightest things) and he was violent towards me. Honestly I never blamed him for the reason why he was violent towards me because when I knew him, he was the perfect guy. I know he has violent tendencies towards his mother and brothers but he always assured me he wouldn't lift a finger on me.. So when he did I figured I must have been a bitch.. This is also what he told me when he left.

Anyway, less than a month after he broke up with me, he found a new girl, and he knew this girl through a friend when he lied to them and said he was "single" (during one of our arguments about something he lied to me about but we DID NOT break up) and his friends match-made him with his current gf who also just came out of a r/s.

His facebook password is still my name and I log into his fb frequently to find out how he is doing.. A part of me wish they will break up alrdy. I want to know how I can stop stalking him and his gf and get mad whenever they post pictures of themselves. I know he is happy, because he does a lot of things for her that he never did with me because he claims "it is gay and a waste of time" (surprises, picnics, taking photos, buy flowers). I have not spoken to him since they got tgt but he messaged me slightly more than a month ago. I did not reply tho, I was a mess when I received that message, cried the whole night. I miss him, I still do.

Give me the gist of the text in a nutshell
<bot>: My ex has a new gf and I can't stop stalking both of them. I still love him and I know he is happy, so I want to stop stalking him. Please help me?
