Some help and ideas on the situation?

There is a guy i' been dating for half a year. Thought about quitting a long time ago, but always something comes up. I'm really afraid to be alone, i always need someone to talk to, some male attention and something fun to do. Besides, I started missing him. He has some good traits, but he also has major problems. His indecisive, he has little respect for a woman, he doesn't really know how to hold relationship, he barely tries to please a woman. Recently we had a huge fight, he insulted me, i got angry and threw a drink in his face (i know i shouldn't have done this, but it really got me angry), we told a lot of things to each other. Then i apologized. The thing is i'm trying to be firends with him, because i don't see us as a couple and lately, everytime i tell him lets do this or that, he is like i don't know. Today i invited him to go to movies with me, he is like I don't know, i have someone leaving at my house and i don't feel comfortable with it (he has his cousins' family and besides how is it all connected). He called me and asked me if i could clean his house on the weekend (? i'm like i'm not your maid, he is like and stop writing me messages, like two is the max, i'm like what the hell). I'm just tired of being friendly and nice. And he is making a joke out of all this situation. Just want to cut my losses and move on. Not my typo of guy. But the problem that I actually developed some kind fo feelings through this half a year and i'm used to having him around, but i don't see him trying to keep relationship lately. So just thinking of giving it up, just the questionis how? How to be dedicated on no contact? How not to break it?
