Why is he doing this to me?! keeps leaving, and i dont have no one to talk to!:(?

I Want to tell you guys the story, but i'll make it as short as possible. My bf broke up with me in december, and I didn't see it coming because EVERYTHING seemed perfect, I could swear that! I met his parents, been over to his house multiple times and we just seemed like the perfect couple, he would tell me things he would say he's never told anyone else before and we're just the type of couple to finish each others sentences because of how alike we seemed to be..well 1 month pes and came the night that me and him were on the phone talking about how much we miss eachother, he kept telling me " baby I miss you so much, can't wait to see you tomorrow, even though I wish I was holding you in my arms right now" so you know we talked more then we said our goodnights, and I fell asleep, then 2 hours later he woke me up by calling me and when I answered he told me, " aubrey(my name), i'm sorry that im doing this I really am, but i just don't feel like I can be in a relationship right now. I'm sorry if this is so random and weird but Ive been thinking about it and I just am not ready for all of this" I was in shock when he told me that, he sounded so serious, which is not like him, he's always the happy guy I know..i just told him, 'wait..are you serious?" I couldnt think of anything else to say because for one, I was in shock and thought he was joking and he just said " aubrey, please understand and don't think this has anything to do with you, because it doesn't, there's nothing wrong with you, i'm just not ready for a relationship" I then said, " well if that's what you want.." yet I was in shock and in denial and he just said.." i'm so sorry for this, and sorry that I woke you up, take care " and he hungup. I thought he would call me back and start laughing and saying he's just playing, but he never did and thats when I started crying like crazy, I cried for 1 week depressed, not wanting to move, just looking at my phone. I would continue telling you guys the story but I dont want to make you guys have to read so much, so in short..1 month pes, he contacts me and he tells me how i've been and well I just made small chat with him on FB and he just kept acting like nothing happened, so now supposedly were cool. But last 3 weeks, I ran into him in a kickback and it was him and just the people im used to seeing him with, friends. He broke down and started telling me that he misses me( he did this in private with me in the bathroom) and started telling me that he was just scared of how much he was starting to feel for me, that he was scared of everything and didn't know what to do, and well I told him how much it hurt me and he said he wants to take away that pain and be with me again, because he missed me so much and he realized it all when I didnt contact him for 1 month. Well to my misery I did get back with him because I love him, and well that week was probably the beest one for me because I went back to his parents house and they told me that they missed me and well we just talked in his room for hours and snuggled and had a great time together alone, it went on like this for 2 weeks, when again late at night he calls me drunk and starts telling me that we can't be together.." thats when I seiroulsy just lost my mind and I told him to tell me what the **** is going on/! and I told him to text me because I couldn't understand him, and he does and says " I'm sorry im doing this to you again, i really am but I can;t be in a relationship, I guess I ended up blacking out at some party and made out with another girl, I really am sorry but I can't do this when I did that to you, i'm so sorry this time," he told me take care. I broke my phone in anger...I really have no one to talk to but really, WHAT THE ****? WHY ME? I REALLY AM NUTS IN THE HEAD RIGHT NOW AND NOBODY TO TALK TO! why did he do this to me? get back with me if he's just gonna hurt me like this once more. It took me 1 month to recover, now I feel like I can't! HELP! whats his problem? and will he regret this?!
