Initially, you may be taken with his unique openness and vulnerability, since you haven't encountered this in other males you've known. It's refreshing to find a guy who doesn't censor his feelings/thoughts, and seems emotionally accessible! It's incredible that this man appears so completely without guile, he almost instantly puts you at ease and inspires your trust.
You're appreciated for your qualities and attributes, and admired/respected for the woman you've become. He's extremely attentive at first, and wants to be with you constantly--which is like music to your soul. As this courtship picks up speed, you feel fortunate to have found such a considerate, loving, thoughtful man--but just as you begin trusting that his pronouncements of love are genuine and start envisioning your future together--things change.
Casanova makes sure you know how grateful he is to have finally found you, because you're "like no other woman" he's ever known. His enthusiasm and glee seem authentic: One of my ex's would initially remark how great it was, that he'd finally met a female who was his "intellectual equal." This elicited my prophetic response; I hope that what you're loving now, you won't start despising, later. Yes, I'd had warning signals just like you--and foolishly put them aside. He'd just recently left a long-term marriage, and I knew better. While he had dated a few others in-between, my concerns about the wisdom of our timing, were always met with vehement assurances that he'd wanted someone like me, his "whole life!" Before long, I threw caution to the wind~ and it came back to bite me on the fanny.
