Ok, none of what you have done is "wrong".

Getting a STD and not knowing about it? Happens ALL. THE. TIME.

Actually, its quite common for people to have no symptoms, and that's why they don't get checked.

Sexting is something that most of the free world does. Again, not wrong, its just intimate talk between two partners that happens to be over the phone. I mean geesh, let's go back to the dawn of language and outlaw sex talk! LOL.

Changing your behavior because it might affect your future husband?

Sweetie, you've done nothing shameful! I could see his argument if you were a street-walker who was selling her body for money (even though I still don't judge these women), but from what little (and I do mean "little") you've done?

You have nothing to feel ashamed about.

So here's the thing.

Your guy is controlling and doesn't trust you.

A man who wasn't controlling wouldn't have this kind of attitude toward you.

A man who trusts you wouldn't be hacking into your private accounts.

Do you really want to stay with a guy who wants to control you and doesn't trust you?

At 6 or so months in----where you are now----you start to see much more of the real person and not the lovey dovey person you started to fall for. Knowing the real person underneath it all is so much more important.

I'd be hesitant to advise you to stick with this guy. Rather, I think its time to let it go and move on. The right guy isn't going to hold your sexual past over your head. (Especially with only 3 partners? Does he want a virgin!?!)
