I completely understand your confusion on this issue. Been there! I truly think that I'd still be stuck in H's one-foot-out-the-door limbo if I hadn't taken a stand and let him taste the loss of me. It didn't take long for him to freak out and realize some things needed to change. It was scary, and I had to do it understanding that I just might end up without him, but it was certainly worth taking that risk.
You are an A-MAZING guy, and you're doing a fabulous job of showing her that your R can be great again. We all have our own paths to walk, but it might not hurt to get used to the idea that at some point you may be on your own. It's scary and painful, but liberating in a way too.
