Here is your problem. As the LBS, no matter what you do, he'll say it's the wrong thing. If you fight and chase he'll accuse you of smothering him and being controlling. If you DB he'll claim he wants to be chased and fought for. You're darned if you do and darned if you don't..... According to his words.
But if you let him go, give him time and space, then all these other dynamics we've talked about could eventually come into play. He'll get curious why you aren't chasing, calling, hounding. As you distance, he'll get the urge to pursue. Whether he does or not, none of us know.
What I can't tell you is I've seen dozens, maybe hundreds of these sitches, and pressure and pursuit work in less than 1% of the cases. DBing only gives you a 50/50 chance, less the worse you are at it. As you can see, the best chance you have is to DB the best you can. But it isn't up to you or anyone else other than him ultimately.
