Why would a single man purchase sex when he can be ...

I would assume he wants a 'nice' girl at home but wants to fulfill other desires elsewhere.  My question is why would he be the one to ask you to leave?  I would have packed up and moved on, leaving him to wonder what the hell happened.  He doesn't respect you....bottom line.

What closure do you need?  Your man was having sex with the  'girls of Craigslist', at the same time he was having sex with you.  You have no way of knowing what he exposed you to.  Make an appointment with your GYN and get yourself checked out.  He thought more of his own physical desires than he did of you and once you were on to his little secret, he asked you to get out of the way.  Move on..... count this guy a loss and find someone who will treat you with respect.  You deserve more and as soon as you realize this, you will look for a man who offers more.  Good luck

Jada_Lynne , You Go Girl !   Leona , I am with Jada I'd have been gone before this man could utter one word to me .  Don't waste the energy it takes to lift a finger to ask a question about a man like this .  He's not worth it and I use the word Man loosely .  There's many good loving honest men in the world all of which this guy is not .  It is very clear he doesn't love , respect , cherish or value you .  He is living a dangerous life style , he put you at risk . See your DR .

Because he's a complete idiot. A moron. Get a new boyfriend, this guy is too stupid to live. Seriously.

You can't see it now but he's doing you a hugh favor. He doesn't want to be with you and without defending his actions, at least he's being honest with you about that. For those of us who seem to advise you to "just move on" and make it sound like a "no brainer" have never experienced, or have forgotten what it's like to have been seriously emotionally involved and had it all fall apart for no reason we can understand. So instead of focusing on the greater good, you are tearing yourself apart trying to understand the why's and nothing said here is going to change that.

Here's my advice, understand that this is a natural process and in time it will pass. You obviously had some great experiences with this guy and one day you may be able to remember the good parts without being hurt too much by the bad ones. I encourage you to try to do this because as long as you carry the bitterness and resentment the longer this guy will control that part of your life.
