Who is wrong or right?

This is really long but please do understand the situation im in, I really need help and I dont know whats going through my mind because of it. Thanks

Me and my ex broke up 2 months ago, I kept asking him back after I broke up with him because we kept arguing and I had enough of him blaming everything on me and making excuses so I felt like I had no choice but break it up. We’ve been together for a year and 9 months and I loved him with all my heart. He broke up twice with me before and I broke up with him for the last time. When I kept asking him back and we both made our minds up to be not together, we left things uncleared. We didnt like each other because we both said things we didnt meant to say but hurted each other with it.

Anyway a month after our break up, I was actually fine with my life and my ex found out I was talking to this guy and we had another arguement, he was telling me that his nothing to me now because Im talking to this other guy when he kept his feelings for me and all I do is try and get rid of him. But he told me after we broke up that everything we had meant nothing to him, and that we cant have the dreams we always wanted and I still wanted them but he didnt. So we had another arguement, as I was telling him that his the one who left things like that and his having a go at me for trying to move on. The at the end of our arguement I just asked for the truth, and he ended up telling me how much he loves me, cant stop thinking about me, misses me and how much he wants to be with me but cant.

After a few days we met up and we ended up kissing each other and all my feelings went straight back. We couldnt be together because of everyone disapproving with us being together so I told him, we’ll see in 2 years time if we still both have feelings for each other, the we’ll see what happens then. We kissed and he kept telling me how much he wants to be with me then, and how much he never ever gonna forget me. We were fine, everything seems to be going ok, Friday he spent his time with me and my friends and we ended up kissing each other and he went on saying how much he loves me and if he ends up being in a relationship or not he’ll still be there for me; for a cuddle, someone to talk to, anything, he’ll still be there for me no matter what. I told him the same things. I told him if he does get into a relationship ill be there for him no matter what. Ill support him, I wouldnt get upset if he does get a girlfriend and all that. I gave him my word, and I pinky promised it.

Since then, I never talked to him on msn. He never went on anymore, I figured he blocked me. All my feelings for him went coming back to me. I loved him all over again. Then Sunday night, my friend called me and asked if I was ok. I was so confused, then I found out from a social site that hes in a relationship. My heart dropped. He never planned on telling me. Not even a single word about her, he kept kissing me, telling me he loves me and then he gets into a relationship, doing things with her all along behind all that. And I got no message from him or a call or a text. But instead he blocked me on msn, not even a word to me through there.

I got upset and cried… all my dreams, hopes went crashing down infront of me, all over again. I hated myself, hated love itself. I refused to talk to him, because for once my bestfriend was actually willing to support me instead of telling me off for being with him continously. But I just broke into pieces and not a single word from him to find out if I was ok or to tell me about hi new girlfriend . A few days after, I messaged him and asked for the promise ring back that I gave him a year ago. It took him 2 weeks after to actually give it to me, he was stubborn towards me, kept giving me evil looks, and kept storming off everytime we happen to talk. Ofcourse I ignored him gave him the cold shoulders. How can I be friends with someone who I gave my words to, willing to be there for him if he ever does get into a relationship and have nothing from him, not even a hint. He knew me better than anyone and he knew I’d love to hear things like this from him instead of finding out online. But no, nothing.

We kept being cold towards each other until a few days ago. I actually said Hi to him for once.. nicely. And he had the guts to tell me off, for being how I am, for not talking to him and for giving him the cold shoulder. I told him exactly why. But he still had the guts to tell me how to act towards me so I shouted at him, we argued. We kept arguing, and he still wanted me to talk to him like how I used, like the “girlfriend” he once knew.

I wished him happy birthday a day after, for this saturday and he still had the guts to show that my attitude upsets him, being stubborn as always and cold. I told him that he didnt even say sorry or appreciated that I wished him happy birthday and that how can I be there for someone and be friends with them, who cant even tell me the truth no matter how much it hurts. He started swearing at me because I told him I dont care anymore and all that.

So what should I do? Was I wrong for being mad at him? I really dont want us fighting, especially that we arent together anymore.
