I empathize with your wanting answers and results NOW; it's frustrating to have to wait and to keep quiet when you want the R talk and want to know what's happening. In a very real way, I think he owes you a few answers. Unfortunately, if you push, you push him farther away.
The bottom line is this reality, I think: he has made very clear that he is not willing nor able to give up OW right now.
No matter what you do or say or how loving and upbeat you are, this remains how it is at this point in time. His A has not run its course. I think everyone here is in agreement that it will, sooner or later. But only time and patience will work.
So YOU have to work from that. And only you can decide how you want to do it or what's best for YOU. Should you just go on and GAL without H but be friendly and available when he contacts you? Should you give him an ultimatum? A time limit? You have to be careful with those because if you do, you HAVE to follow through with it. You are the one who knows yourself best and your H and what would work best for you with the least amount of pain. I understand your feeling of enabling him, too, but unfortunately I don't think there is a way around it without losing him completely.
But if this situation you are now in is driving you nearly insane you need to find a better way to deal with it. And I don't think pushing or nagging is it. He is where he is and you can't change it.
When you think back over the last few months, it seems every single personal R question you asked and R remark you made got you a response you did not want to hear. Am I right or wrong with this?
