Okay, two parts to this, the love, and the tough love.

Love first!

You're not a fool for giving someone a second chance. Everyone makes mistakes and everyone deserves a second chance. Not, maybe, a third, forth or fifth one, but at least a second one. Even if your dad didn't like him it's not fair to say that by picking him you shouldn't contact your own dad again. Remind your dad that the first guy you have ever, and will ever, love is him, and you need him to be there for you.

Now for the tough love.

You're sorta waaaaaaaaay outta line. Yes, you two are in a relationship and he SHOULD be honest with you. Just as you should be honest with him. Right now you're not, so why should he? And yes, you are being dishonest in how you're treating him. I'm not saying you don't have every right to be angry, or to not take him back, but if you do take him back you have no right to control his life like that. If you don't trust him then don't take him back, don't set major conditions for it. He'll only resent you, and try to sneak around. Besides, why would you want someone back that obviously doesn't want to be there no matter what he seems to have said?

But, even with that to tell him to quit his job, that's majorly extreme. Specially in this economy where he may not find another one. You could ask him to limit his interaction with her, you could even ask him to not talk to her outside of work. But you can't force him, and as you can see, by making it that big of a deal he's now doing it 'behind your back'.
