@Sparkles333,
I agree, he has a lot of growing up to do.
If you are a virgin and have been with him for two years, does he think that he may lose the prize? Does he think that you don't love him enough? That you are changing, as in growing older, up...
What ever his thought pattern is, he is very in-secure and hides behind his words in hope that you run back, crying, saying you are sorry and giving in.
He is quite the card.. And it's backfiring. Often a teenager "guy" or young 20's takes longer to grow up than a woman, even if you are younger.
Going onto POF, what did he do, google dating sites? RSVP would come up first... I see red flag there in that regard... POF has a Forum, and then dating, RSVP is dating... only.
No one owns you, only you, remember that, but also remember that people have feelings and communicating properly is the key... Whilst he needs to grow up, he needs to not fear if he is in a proper loving, relationship. If you have shown that to him, that he doesn't have to fear, that you love him and he still has acted like this and tried the blame game and the immaturety and the in-security, he's not ready for a relationship of trust and that's the relationship you need right now.
Have a think.
