He's definitely NOT thinking rationally. Before he met you, he didn't have you. He "knows" already what it's like w/of you. I'd tell him if he wants to go, fine, but don't come back. What he mentioned sounds like a lame and dumb excuse!
I realize you've been with him for a while, but this situation he wants to be in just doesn't sound right to me. Truthfully, I'd be looking at this like it's a breakup, not him going off for some "test" or "experiment".
