Hi PL....it's totally normal to feel attracted to someone who is paying attention to you...I did the same thing. I met a guy when H was gone for 2 weeks (months ago) and we hung out a few times.....it was definately something that wuold have went further if I wasn't M and he wasn't a prince of a guy to not go there b/c I was M. But, i had thoughts in my head....bad thoughts....but you know, I'm human, I'm not dead. It just made me feel good to hang out with a man who told me that he had an amazing night with me. One that hung on the words I spoke, who seemed interested in me, not disgusted.
I thought about H...and realized that during our M, it's how he felt at times, which is why he lept to OW validations. He admitted that. It's human. It's horrible, wrong and all that, but still human (as my friend reminded me).
If nothing else, all of this mess has made me love and respect H in a very different way...not as my H and all that must come with that....but to see him as a human--with flaws and greatness.
