Men: Need your advice on this one...?

yeah he's just using her for and saying what he thinks she wants to hear to keep the "friends with benifits" going. He's getting jealous if she talks to anyone else because he doesn't want her seeing anyone else and loosing his "fwb". Calling 20 times a day is just another "i need to know what your doing because i don't trust you tactic". Since he's busted talking to another girl online i wouldn't be surprised he's been lookin else where for another FWB relationship or a relationship with someone else.
