Help,, very sad :(?

So I met this guy and he quickly talked me into moving in with him (I was on the verge of moving to a new apartment and he just convinced me to move to his instead). So my very dumb self agreed to move in with him. The whole time he was pretty controlling, protective, etc and I let it happen because in a way I liked it (I know smh). He liked telling me what time I should be home etc but at times when he would go out with some friends they partied hard and with girls and I didn’t like that. On this particular night he was out all night and of course I felt stupid sitting at joke waiting for him while he was out doing his single man activities. I packed some of my stuff and left and by the time he got home (the next day in the afternoon) he noticed I was gone and he freaked out started blowing up my phone and I told him I was done. He instantly packed some of my stuff and made me come pick it up asap. When I got there he was mean, aggressive and he broke my phone, pushed me around and literally threw me out. I was left sad and confused but also feeling so stupid. We stayed in contact because I’m dumb. And he had been crying and begging me to come back home. Said the reason he acted this way was because he is already so attached to me and it hurts that I play with his emotions. He convinced me to come back to him by the end of the week. He said we could do this and we could work through out problems etc. the end of the week came and it was a very stressful time for him because he was stressed out with work and other stuff and as soon as I gave him some attitude he started acting the same way again. Extremely rude, disrespectful etc and he told me he was done and didn’t want me to come back anymore.

It’s been a few days and I am so sad and depressed and confused. I feel stupid. I have expressed to him how sad I am feeling and he is being very cold hearted and saying he does not care and he’s over it and that I should move on as well. I have noticed that this is the pattern so many of my relationships go through. The men start off my being so “In love with me” then as soon as I start calling them out on their behavior they start doing a whole 360.
