My two cents, I don't think it would hurt to bring it up in the context of conversations with her. I've said similar things to my W and I think she appreciates the fact that I'm trying to better myself while at the same time giving her the space she needs. She even told me on several occassions that I don't need to improve as I am the best already (ok, if that's the case, why the problem before us???). I guess that's where I vacillate as well, if she initiates talk regarding feelings, etc., I don't think its a bad idea to touch upon the subject, but not dwell on it.

That's my opinioin, for what its worth.
