Thank you for writing in to Just Answer.
I'm sorry to hear that you went through this experience.
What you describe it sounds like this particular man might have unresolved issues/conflicts with his wife and as he is progresses in the counseling he is realizing that some of those unresolved conflicts if resolved might actually bring him closer to his wife. In other words he might be realizing that certain miscommunications or misunderstandings were at the heart of their estrangement. As a result he probably wants to give things a fair shot and see where the chips fall.
On the other hand, in spite of knowing you for a short duration (6 months) it sounds like he is clearly fond of you.
What makes this hard for you is his going back and forth - i.e. he decided that he wanted to be with you after the two of you took 3 weeks off, yet now he has called it off with you.
In one sense what he is doing makes sense for the long-term since you probably wouldn't want him to be all gaga right now but waver about this relationship and go back to his wife at some later point. So it's good that he's working through it now instead of later.
My recommendation would be to give him some more time, as much as you're comfortable with and see where this goes. I wouldn't wait indefinitely. His telling you that he loves you and thinks about you certainly adds
to the complexity since he has called off the relationship with you. That is why I would encourage you to ask him to not complicate it so much and to only take this forward if he's sure of what he's doing and if he can let go of his ex-wife. But to keep you hanging this way is not very fair to you. If he's unable to make a concrete decision soon as to who he'd like to be with, I would encourage you to consider moving on.
I hope this was helpful.
