IMO the single most unproductive and damaging thing a LBS can do it hang onto a WWs words. Unfortunately this is quite common.
Right now especially being type A you are under the "illusion of action" where you feel you have to do something To convince him that staying with you is the right choice.
If you want to so something then your action should be to drop the rope and let him go. Lead a kick a$$ life. At some point he is likely to have second thoughts about his decision. If you're leading a great life he will be tempted. If you have made no improvements and are offering the same relationship he will likely keep moving forward.
