Well ...

Let's be fair.

If what he wants is a manipulative relationship full of insecurity, distrust and deceit where he will never tell her but always be suspicious of her every male friend or relation then he should stick around.

The OP wouldn't dare reveal his trap at first because she has every right to dump him on the spot. So he will remain with her but act like an ass because he thinks he's got one up on her. If she has any self respect she'll become more distant because who wants to be with a person who is brooding all the time? Maybe she'll try to find out what's bothering him - at first he'll say "nothing" but, inevitably, if she hasn't left him already he'll confront her with some lie that someone told him about her virtual flirtation (or something to that effect). Or he'll use his virtual alter-ego to hurt her feelings in order to either punish her and/or drive her to him. In either case he'll feel better about himself and proved how terrible his girlfriend is. Since he's whipped he won't want to leave anyway but at least he can feel clever about it.

If he tries to come clean (which is the least likely possibility, it seems) she'd probably leave him on the spot if she has any self-respect herself.
