I don't know. Maybe it's because I think PM is a great guy and I am rooting for him, but I just want to say, keep it up. Don't view her coming towards you as a time to back off or set boundaries. Let it happen and see where it goes.
I like this...and agree! Maybe all that patience is finally paying off?
And, yep...you two are consenting adults. You both know "what's what".
As long as you don't feel demeaned by it, and you aren't demeaning her (which you aren't...cause you're an awesome guy)...then, just keep doing what is working.
