Smell the roses... you say you are both commtted to each other. No he isn't. If he was he would have taken his profile down.
He is using you!!!!
PS this from a man.


I would not only be changing my locks, I'd be checking my bank accounts and credit cards. If he is using you for support, who knows what he is capable of. Might not be malicious - could just be your ordinary garden variety cheater but I'd be checking.
If he's committed, he shouldn't be trolling the internet looking for something better. Time to move on IMHO.
