Dear girl, it WAS infatuation. True, real love takes TIME, takes really getting to know someone,. I'm not saying your feelings weren't real, but all love is just infatuation in the beginning.
This hurts you so badly because it is all wrapped up in your childhood abandonment issues, and in your deep-seated fear that you are not enough. That's what you need to be working on with your IC.
And instead of feeling "less than" because he's flirting with that creepy woman, it should be making you view HIM as "less than" . He's not the man you thought he was.
