I hope you will stop being so hard on yourself. You did nothing wrong here, HE did! Luckily you found out before things went any farther and you became even more emotionally attached to him than you already were.
It is all a learning experience hon. You cannot control others, and you cannot change what has happened. All you can do is learn what you can from it and move on. Hold your head up high as you did exactly the right thing.
Please don't let this shelter you from meeting others and jumping back into the dating pool. There is good and bad out there. You just happened to get a bad one....the next one may be your prince charming. But you won't know if you don't try
Hang in there Juliana...you are doing just fine!
Hugssss
