He told me while we were living together that he never masturbated... then it turns out he was, and I suspect because he was, that he was also using porn. I had a rule against using porn, that he agreed to when we first met.

Then he was taking customers' cars home with him to save mileage on his own car. This is a new behavior since we had first broken up. I asked if he gave these particular customers his cell phone so they could call him at night at home. He said "No". BS. He gives customers his cell number - I've seen messages from customers in his phone. So I gathered that he's also talking to his customers from home, including a female customer whose car he had who is our age. He told me her age.

This simply just opens the door to other potential affairs.

I do NOT trust him as far as I can throw him.
