Is it possible that he is waiting to see that you really, really want the M forever?

Is it possible that the immense amount of committment and love you seem to have for him he just hasn't accepted / realized.

I really, really thought my W didn't care much for me and would eventually leave. This despite spending a bit of time together, going camping, ML, etc.

He may very well know how you feel. I'm just asking in case you didn't ask yourself.
