I'm going to take you to task on this.
It's 100% possible to be in a relationship where the wife does not communicate and values around the kids changed in her mind but she never told him. I've been thru that so ur assumptions are simply that assumptions in my opinion.
From my pov and possibly his, you decided u knew everything about the man and got turned off because he was willing to be vulnerable. Men don't get a whole lot of help figuring out emotions and we do it much differently than women. He got judgement and rejection in a difficult time.
My therapist would ask me if I self-sabotaged by not even giving someone a chance to prove who they are and who they are becoming. I mean, here's a person willing to be open and honest with me and rather than communicate I projected my insecurities on them instead of opening up and connecting to that vulnerability. Was I the one not ready to move forward?
