"And he is consistent and persistent."

So how's he managing to hold up with your insecurities and emotional downs without him walking on eggshells? Can you share your insecurities with him instead of getting emotional?

"I see he is trying, I don't see that it's enough for you. So, I will ask you..... what will be enough? I sense you are waiting for the other shoe to drop, almost as if you are testing him?"

I've been seeing exactly this for a while. Are you trying to beat him into some shape of your choosing? If so you could ultimately be disappointed. Where does your commitment end?
(I've see a case or two here where a potential WAW apparently kept beating and beating the apparently "emotionally abusive" H into getting everything exactly how she wanted it, but nothing he ultimately did satisfied all her requirements and any small occasional slip up by him was enough to set her off on the warpath again. She ultimately filed D after all the effort the 2 of them put in. I don't see this happening to you any time soon but, one thing leads to another and another, ...).
