The best part of this whole deal is that the boyfriend gets a free walk. Most likely Charlotte wasn't trying to get with Jez's boyfriend, it was Jez's boyfriend fucking around trying to hit some new puss(Charlotte). So, he's out and about looking to get some play, Jez sees "potential hubby" talking to fresh meat, Charlotte, and Jez blows up on Char.

That's one charismatic muthafukkin suitcase pimp.
