I agree with all said here. Very bad crap you had to go through, and it's a story I've heard many times here before, from people who are much older and supposedly wiser (we all know age doesn't bring wisdom, necessarily, anyway). There are many women here who prey on foreign men (as well as foreign men who prey on women, but usual it's a business transaction and the woman is consenting).
I know someone who had an affair down here (he was single) and the woman stole everything he had, including his business laptop, which had pictures of him and her on it in some compromising positions. The woman tried to blackmail him later and when he didn't pay she sent the photos to everyone in his email contact list, which of course ruined his reputation at work and he ended up losing his job and going into a downward spiral. The woman had a male accomplice and they were later arrested for doing the same thing to another gringo.
As also was said, you're young, you're in good physical condition and you haven't lost anything but a little pride perhaps and some money, which is easily replaceable over time.
Don't beat yourself up about this, it happens to the best of us.
I'd leave the deposit as well and just go, letting them know afterward you're not coming back. There is no way they'll come after you at home and the deposit should cover most of your penalty (two months breaking a lease in the first year if I remember). If you still owe a little on that after you get back, send it down via Xoom or Western Union or something and count yourself paid up.
