Unable to get over

Hey guys, I dont actually know why im posting here, just to release a bit. I broke up with my boyfriend 2 years ago, we had a 3 year long relationship and lived together the last year, we kept in touch and there was always the hope to get back together, not only by my unending love but he also fed that hope continuosly till last august. We end up having a really bad fight in which i urge him to open up and tell me everything and be honest about it all, long story short he knew there was nothing left since june 2015 but was "too afraid to lose me". So now here i am, trying to get over him and im fucking unable, everything triggers a memory of him, i've been fucking around to try and forget and after each time all i can think is how much i miss him. Currently we are blocked from all social media and possible contact. I feel obsessed about him, i feel bad with myself about not being able to put him behind me and being so fixated; but at the same time i fucking miss him, i miss his hugs, his smell, his warmth and its fucking killing me.Any advice? Or whatever you may want to say is also welcomeTL:DR Obsessed over my ex cause he feed my hopes of getting back and now he shoots them down. Unable to forget and get it over. Advise or whatever welcomed.
