<human>: Guy 24, moved in, with girl he'd been hanging out with for a month and slept with for about two weeks after he moved in.  Then he says he doesn't want to be her bf, sleeps with me, then goes out with her (lies to me), has sex with me again over a week or two.  Night after we're together his bike is stolen and he goes with her and has sex with her, hangs out with her for four more days, then doesn't talk to her for six weeks.  
   
During that time tries to have sex with me off and on.  Then he brings a new girl over I give him two weeks notice, then apologize a few days later and take it back.  We fight, I talk to his ex and find out about the lies and sleeping around.  She sleeps with another guy that night but lets him move in the next day, saying she's not into him anymore but he can live there.

He slept on the floor for awhile, complained she was out all night last week, and that she was dressed to go somewhere fancy on friday, but I still think they're sleeping together, any ideas?

If I wanted to get this guys attention again (just curious if it's possible) is it possible?

Can you give me a shortened version of the text?
<bot>: Is my ex-roommate/lover sleeping with his ex whom he lives with in a studio for a month, but she won't do anything unless he wants something serious!
