<human>: We started dating just over a year ago and probably moved in way too quickly but anyhow. I'm 20/f he's 26/m. He dodges all responsibilities likes to take jobs until the first paycheck then stop going so he gets fired. Repeat. He hadn't contributed to more than 20% of the household and got mad when I didn't do my 80% perfectly all the time, etc. He also talked to other girls in flirty ways on facebook and compulsively lies to me and swears he'll never do it again but I don't want to get back together with him.

He owes me $750 currently. Money from my account that came out for his share of the rent this past couple months as he failed to pay it himself. Landlord is now asking him for the very late portion he owes and I have no idea what to say to her as he won't answer her so she is asking me about him. He treats me like dirt and is clearly unreliable that's why I'm moving out. He wants to show me his changing and stay friends etc. I didn't agree at first but he guilted me. Now I'm not so sure.

Can you condense the text into three sentences or less?
<bot>: should I stick in contact with cheating, responsibility dodging, negative ex (his idea) and slowly get paid back several hundred dollars or should I just cut all contact and try to take it up in small claims court ?
