no, he sounds like mr responsibility.

doesn't he have more self respect than that or doesn't he care?

and as for his choice in partner...

WTF?????

maybe... (gently here) you might want to have a look at WHY you feel attracted to this guy given his history. i'm sure way he tells the story it is all their fault but it takes two to tango. and... i'd keep the hell away from him personally. i mean... if this is how he disrespects his present girlfriends then this is likely how he is going to disrespect you down the track.
