I think I addressed this on Mama's thread. It applies to you too, I think. This is one of those points where you just have to make a decision and then live with it. I think you know where I stand, or rather what I did in my sitch when it got to that point. The jury's still out in my case. You just have to decide what you want and then go for it.
Could you be opening yourself up for more pain? Yep, but at least now you know it may be coming, which is a hell of a lot better than the blind-siding that happened the first time the bombs fell, right?
Trust yourself. You seem to make good decisions. Make another one and then trust it's right simply because you made it. It's all you can do my friend.

P.S. Like I said, there is more about this "decsion" making on mama's thread.
