How to truly get over someone and let the past go?
I don’t know what to do anymore. Me and my ex have been split up for 6 months now and I’m still not over him no matter what I do. I never wanted to date him, but he kept trying it on with me for two months, so eventually I caved in and gave him a chance. We started as a casual thing because he had split up with his girlfriend a few months before and did not want a relationship, so we would always split up and get back together but during this time he took my virginity. After 3 months, he asked me to be his girlfriend and treated me the most amazing way for the next two months, which then I discovered I had fell in love with him, hard. He was my first love and only love so far, I did not tell him for fear of him not returning the feeling. After this he started to pull away which made me feel alone and unhappy, I could feel like he didn't want me there. Then eventually he broke up with me again saying he wanted to be single as he had not been for 5 years with various girlfriends. When this happened I stayed in my room crying and not eating and I told him how I truly felt about him and for the next two weeks we kept seeing each other and sleeping with each other until he begged for me back again.
I took him back and the first few days were wonderful again, but I couldn’t shake the feeling that I was so angry at him and resented him for the way he was treating me and I was considering breaking up with him, but I just wasn’t strong enough at the time to do it. He would ignore me at parties at talk to one of his ex’s who ididnt realise was his ex at these parties . Eventually a group of us including him went out one night to a club, where he was being the most romantic he had been for months, but later on in the evening, I was walking round the club and saw this girl pull him right in front of my face and he continued to pull her. I slapped him and he ran off out of the club and refused to speak to me for days and refused to apologize. Therefore I decided to end the relationship, but had to over Facebook as he wouldn’t see me face to face, we met up after a week or two and was friendly but he later told me he never wanted to start anything with me again, a week later he pulled this really ugly girl who was friends with one of her friends and put all these photos up on Facebook of the two of them together. He came round a week later and sat arrogantly in my room saying “yeah im a ******* aren’t I?” and telling me I was ridiculous for not being over it within the space of 3 weeks and talking about the new girl, to which he left because we started arguing. Ever since then we have argued and insulted each other over Facebook, and I have gone out with someone since which has ended because I wasn’t over my ex. I have suffered panic attacks and depression since the night he cheated and I have been to see a counsellor who didn’t help me at all, she just told me to exercise and let it go. I have dated various people and met new friends and created a whole new life for myself since then but nothing helps, I just feel so empty inside and I constantly run into my ex and his new girlfriend and he either smiles at me or totally ignores me but still stares at me. It kills me seeing it still. How do I get over this?
