I avoided this thread for a while, expecting someone else to say it...but don't get yourself hurt. This guy didn't love you while you were together, you read it for yourself. What makes you think he's changed? Your friend is obviously worried about your decision, and probably think you're making the wrong one. I recommend you move on and find someone different who will treat you better. He sounds very jealous and controlling, especially asking if anyone has touched you.

We all get screwed over once, but you deserve it the second time around if your stupid enough to go back to that.

But whatever happens I wish you the best of luck.
