Hi loveuall, great that your PW / BWD sessions are working on him!
But i want to add: Dont give yourself away to that man until he makes it known that he wants to be with you.
What you are doing is helping him take the edge off, he gives you small crumbs of himself then runs back to his real life.
Go no contact and if he does contact you only maintain communication if he is respecting you, willing to take you out on an actual date etc.
The fact that he is involved with a married woman has alarm bells ringing already. Try not to get caught up in their mess. Keep up the technique on him though, just be mindful that he is keeping his options open right now.
