Ok, since the season just started last night, I'm sure my Grey's Anatomy references will get more frequent and here goes the first one.
Last night on the show (if you watch, then you already know) there were two characters who are dating but not talking to each other right now. Throughout the whole episode, it was clear that both of them WANTED to talk and maybe even more, but each of them had their reasons they were using as excuses not to.
While the issue was not resolved on that episode, it's obvious that the writers will have the characters come to some kind of new perspective because of some life altering event and they will realize that they have been stupid to be acting the way they have.
What does that have to do with you? Well, I think that maybe your H is in that place. He has some kind of pent up emotions, some trumped up excuses why he doesn't just "jump all in" with you and it may simply take time, or some kind of "ah-ha" moment when his perspective makes that shift and he realizes that, as Mr. Miagi said, "there is no try, there is only do." (or was that some other wise master?)
At least I hope that's the case. It seems like your H is peeking through the wall but is still afraid to leave it's relative safety.
I am proud of you for maintaining and I hope you can keep it going.
