Am i still wrong? I need urgent help!!!?

2 and half years before i cheated my guy , i used to meet another guy when in relation with him and was some what physically related (not sex). i realized my mistake immediately and since then i am trying to get him back. my guy thinks that i have had sex with the another guy, but that's not at all true...these 2 and half years i did what ever he said, whenever he used to doubt on me, i used to prove myself and this happens almost each and every day. i did each and every thing possible to get him back and gain his trust. I made him feel good. I used to take out so much time for him. I bunked my lectures for him. whenever he demanded, i satisfied him even though he dint give me any kind of commitment. he never shows his love for me . whenever we fight, at last i used to make up his mind, i used to say sorry, even when he was wrong....i always used to think that i am facing all this just because of my own mistake. I let the things go on....But now, all this is irritating and disturbing me so much....He is not ready to give me any right over him, he doesnt answer my questions,he wants to listen my and my friends(Girls) conversation, he tries to prove me wrong in each and every thing i do...whenever there is an argument, he brings up my past...i dont know what to do....should i still tolerate everything and be quiet because i was wrong some day, or this is emotional abuse? I wanted to know, am i still wrong?
