Pinky you seem to have a penchant for attracting predators when your M is on downturn. lol
Sorry, but anyone who approaches you to go out with them under your circumstances is a creep and you should steer very clear away.
"I am a good listener" was the real red light t here...what he means is "I sense you are vulnerable and sad and I don't mind getting involved in something morally objectionable if there's a chance I can get some action"
Stay away from other men right now or you will end up making the same mistakes your H made. And right now maybe you can even understand better how he got into this mess.
I really blame marriage predators more than WW spouses. They are like carnivores who sense a weak member of the marriage herd and try to corner it and end its life prematurely...makes me sick to my stomach how morally compromising some people can be.
If I understand correctly, you are a) still married, b) still want your marriage, and c) are still living in the same home as your H. HOW on EARTH does this indicate to anyone that you are romanctically available? lol
And the B.S about I'm a good listener? Well, if he's such a good listener then why can't he read the signs that you aren't ready for a relationship? Those three I just pointed out should be clear to "a good listener"...sheesh
Anyhow, my advice is the same as others have said, stay away from other men right now and DON'T send out signals you are vulnerable...that brings them out of the wood work. Sexual predators love emotionally vulnerable women, they are easy prey.
Well done on the swim visit, you didn't interact and you left early to do something else...excellent detaching effort there.
