First off, that sounds like a really positive convo you had the other day! You handled it so well, and should be proud!
It certainly sounds like your H is turning back into the H you know and love - or maybe even better. Keep it up with your boundaries and your awesome DBing, you are doing so well!
Oh, and about the flirting - I agree with the others. If you are just not a flirter, and have no desire to be one, then no, I wouldn't flirt. I think it would be awkward for you and he probably wouldn't buy it anyway. But I am sure that you have flirted with your H before . . . maybe in a more subtle way. Make inside jokes with him, be light and happy. I think you are already doing that. It sounds like he is beginning to appreciate you for who you are.
