Most Helpful Guy
He sounds like a real treat... I would not loose to much sleep over him! He did you a favour.
I would take you money and run... ask him to pay you back especially if it was a business venture and it was documented.
All guys don't keep other women on the side in case of an emergency. You are much better off. Take the high road, get what you can out of it and then don't bother with him.
