IS this emotional abuse? was i a victim to emotional abuse?

I was in a relationship with a guy for 2 yrs, but the last yr has been very rocking. He has personal issues that he is currently working on and has been depressed for some time. Ive notice that we have been arguing more and more. I have my own personal issues and at one point he told me not to come to him with my problems cause he didn't want to hear it so i didn't. I went else were for emotional support. He eventual told me that i can come to him when ever i need to talk. But everything i try to talk to him or tell him that he did or said something that i disliked it always turns into an argument. He always tells me that i never listen to him and that i chose to listen to other people in stead. When we argue he makes me feel like everything that involves the argument is my fault because i over react. so learned to just not say anything to avoid an argument.When i upset him he gives me the silent treatment for days at a time. and when he's ready he will talk to me like nothing happened. he would say things like i will break up with you if you did this all the time, so i didn't do want i wanted. he tends to buy me stuf or take me out to eat when he knows that im upset or sad. One time i gave him the silent treatment with because he told me not to talk to him and he update his status on msn, with some really mean things because i wouldn't communicate with him. we've broken up a couple of times and when i seem like im really moving on he try to get into my life. And i always allow him to because i love him. He has recently told my friend that he knows how to deal with me and i'll always come back to him. right now where not together. but its killing me. my friend thinks that its hard to get over him because he was emotionally abusing me without me knowing, he was so controlling that now i feel like i need him in my life and cant move on... i have been so depressed for more than 6 months and everyone has been worried about me cause i haven't been myself.
