I can't figure it out

[xoxo88]

My boyfriend and I broke up 6 months ago. Our relationship started four months after a painful break up with his ex. When we met he wasn't over her. During those 4 months he was confused about what he wanted with me, called his ex to make up with her (somebody told me this, so i don't have the certainty it was this way) and a month later after calling his ex to make up we were together. During our 1 month and a half relationship his behavior was just impecable. After the break up i found out he had told somebody else we had already broken up about a week bofere he told me. He didn't even tell it to my face, he used messenger instead. During the relationship i know i made some mistakes, neglecting him and our relationship because of some trouble i had at the time. I was suffering from depression (i didn't even realize it at the time) and i was acting very differently from what i used to be and i was unable to take good care of myself first of all, of him and our relationship. I never managed to figure out if he ever cared about me or i was just a rebound thing. He was always very attentive, respectful, offered to help me many times, invited me home, as i said, his behavior was just impecable, i was feeling amazing in his company. But still, what he did when we broke up, telling somebody else before me and communicating it with me online left me deeply hurt. I don't know if he did it because he never cared about me or just because he was disappointed about the way i was acting and wanted to end things with me as soon as possible. I remember once i got so upset and sad about something related to the trouble i was going through and just stayed home and didn't talk to anybody, not even him. I didn't talk to him about 2 or 3 days when that happend and he seemd kinda hurt. Why would he pretend if he didn't care? So many thing are still confusing to me. After the break up we talked a few times and he didn't refuse to talk to me, he was nice as usual and he even had the initiative once to talk. Besides the nasty stuff he did when we broke he seems a great guy and made me wonder so many times during these months if i'm throwing away something really great or maybe the best thing i should do is give him up for good. The fact that our relationship happened at the wrong time made me wonder so many times "what if...?". Please tell me what you think, did he ever care about me or i was just a rebound thing?
