Hey hey.
For me the answer is simple. You stated that the relationship was unhealthy. What makes you think it will be any different now?
Also, imho, if a man loves a woman he will Never let go. That setting it free bs doesn't fly. He's likely just looking for some action and going back to his past flings. Sorry, that's the way I see it. Just my opinion so take it with a pinch of salt.
I noticed you never did a introduce yourself post. It is recommended to do that. Just a thought.
