Do you think that I loved him or I just cared about him a lot? (Please read)?

Well I ended things over a month ago with this guy named Matt. Everything was fine at first. We met each other in the beginning of last October. We were friends for the first 3-4 months but then I started to like him so we decided to go out. So we went out on dates (nothing official) for about 6 months. We didn't like anybody else and neither did he. He even asked me to be his girlfriend about 3-4 months after we went out on dates but I was afraid to commit to anything because he didn't have that much experience (maturity). I'm indecisive with EVERYTHING. I'm just afraid that I'll make the wrong decision. I think it might be because my mom literally blames just about everything on me. With a combination of the fact that I'm down on myself a lot so if something fell through I would probably blame myself for it. But during the summer I always wanted to be with him. I wanted to talk to him all the time and whenever I wasn't with him I was always thinking about him. I would always buy him things for him when I saw something that he might have liked. But after a while we just suddenly started to get into arguements. He would lie to me about the stupidest thigns and expect me to believe it. He would get overly sensitive whenever I talked to him. But I admit that I made mistakes too because I would always be talking to him about my doubts and he got tired of me giving my lectures. I'm a big worrier naturally. And I don't know how to stop worrying about things. after we got into arguements I was always the first one to text or call him to talk things out. He never reached out to me first to work things out. we would work things out temporarily but eventually it got to the point where things were so downhill that it was hard to fix it. I kept trying and trying but he gave it zero attempt. I kept doing this for months. But then I finally wised up and I had enough last month and I told him I didn't want to talk to him anymore and that I was serious that time. Of course he was thinking in his mind that it would blow over and I would eventually come running back to him in a week or two. So he texted me as if nothing happened 3 days later. And I told him that I wasn't talking to him. He played the innocent game of course. But I put him in his place several times. He's been trying to contact me through facebook and text several times since then and I would answer by saying something along the lines of "You know what you did. You sat back and didn't care to fix things with me while I tried my best. So now I'm not talking to you". It's just I still think about him CONSTANTLY. I think about kissing him and being with him just as close as we were in the prime of our relationship. And I just can't get him off my mind. I even feel bad sometimes when I see him sad in school (he doens't have many friends because he's a standoff-ish serious kind of guy). Did I do the right thing? Did I love him and that's why it's so hard to move on ? Or did I just care about him a lot?
