Hi
Have a really tricky situation on my hands and really looking for advice in order to make sense of this.
Quick background

Married 11 years , 4 kids. Husband had a 2 month affair with co worker 3 years ago. Trying to move on from it but his lack of remorse or marital effort not improving. I have never been unfaithful.

Current situation

Two days ago my husband invited a male work friend he is very fond of our house. I was looking forward to meeting this man as my husband talks about him all the time and I had not met him in person yet.

So far no problem however the minute I saw this guy I was completely attracted to him and felt completely infatuated with him. I feel like a moronic teenager crushing on a tv star it's that stupid. He is extreamly good looking and charming and since then I can't stop thinking about him.

I was so scared and taken aback by my feelings I told my husband that I don't feel it would be right for me to spend any time with or to see his friend again as I was attracted to him and for the sake of our marriage I need to cut off any temptation. My husband agrees with my view however told me that he could tell me some things about this guy that would make me dislike him. I listened as he told me how this guy regularly cheats on his girlfriend of 4 years how he has slept with many married women including one that was 7 month pregnant because her husband wouldn't sleep with her while she was pregnant and many more stories like that. I now believe I must have a mental disorder because I am even more attracted to this creep.

What is wrong with me? I literally can't get this man out of my thoughts. When I catch myself thinking about him I actively try to distract myself but it's just getting worse. I genuinely have not been attracted to anyone a part from my husband since I got married 11 years ago so what is this all about?

I have been honest with my husband about the initial attraction I felt and put measures in place so I won't act on how I felt but I can't tell my husband just how bad my crush is and won't have to see this man again as he lives 1 hour away but my feelings are seriously driving me mad.

Any insight would be welcome.

Thanks
