I think FF brings up a good point, he may come back and not change, that could very well happen. How that would set with you is the question. We can DB until the cows come home, but if I've said it once, I've said it a thousand times, you cannot make someone feel what they need to, to really commit to a loving R. It may just be that your H just doesn't have those deep feelings towards you anymore, or you can bet you bottom dollar things would be different. So, you can love him the way he is and accept how he treats you if he comes back, or, you decide that settling for that kind of R, isn't how you want to spend the rest of your life with someone.. The choice is yours. When you detach to the point where you let go of the need that he is your only choice in terms of a lifelong mate, I think you'll do what you really should do..and thats cut him loose for good and move on if your gut feel tells you he's not going to change the way you prefer him to.
For now, you continue to leave him alone, give him space, work on yourself, stop obsessing, get strong and confident and make yourself a happier person. Those are the kinds of things a WA will notice and perhaps dig a little deeper than they have been if they don't want to lose you...
