I still love my ex and it's been over a year and he has a girlfriend and I've tried not talking to him and I still think about him and get the urge to call him even if he doesn't call me. He broke up with me and went back with his ex in March 2016, I stopped contact with him in May 2016 and didn't talk to him until September 2016 but I still thought about him during that time and called him on private and didn't say anything and he hung up each time. And I talked to him from the ending of September until December. Then I went 3 months without talking to him and still thought about him. And recently I went almost 2 weeks without talking to him and really got the urge to call him to the point where I ended up calling him. What do I do?
