I personally dated a few guys at one time in the past , but I was not intimate with any of them, until I decided to date only guy X and even then I was in no hurry to become intimate. In fact my pretty much true test of whether he was looking possible long term was when he would agree we both were tested for std's" If the guy is unwilling to do so , then he got kicked to the curb.

I think its easy to "fall for someone" but it really takes time to know a person and have trust and respect from both parties.

You will never really understand "why" he did this to you. I would advise that the next guy you date that you take it slow and keep careful watch on your emotions early on... You can go out and feel very connected to someone, But leave it at that a "connection". connection doesn't mean "love" ... It takes time to actually know a person and that can't be done in a handful of dates.
