I personally would give it a 95/5% chance that if you turn him down, he will be drawn closer to you (95% chance that will happen)
I agree with this. Don't know what the odds are, but I agree with increasing your odds. If you have a nice dinner like you described, but make it clear that you can't be sexual with him unless he's all yours, I think he'll try even harder. At some point you have to ask yourself, "is this enough for me being the woman on the side?" If the answer becomes "No", then it might be necessary, for your own self-esteem, to discontinue even the dates. But, you have to do what's right for you.
