This thread is sad in so many ways. Heartening in others.
I cannot imagine being so insecure that I'd try to ruin genuine friendships because of my own jealousy.
One night, a very beautiful woman was part of a party in our house. Far more beautiful than me, and I'm not bad at all. She stayed late, later than most. I was inside with my friend, we'd been to buy wine (kids at sister's), and I looked outside. This model like woman had attached herself to my DH. Hands on his face, body pressed to his, leaning into a kiss.
He didn't know I was home. Took her hands and moved her away from him, very violently shaking his head. Stood up, grabbed his cane, said something sharp to her and stormed inside only to see me and burst into angry tears.
She was his friend, yes. A new friend. But he didn't want her.
His female friends all heard about it (because she had been their friend), and cut her sharply out of their lives because they were disgusted. He was a married man. And he felt so upset by it, not flattered, upset.
I trust my husband. I trust his friends. And I trust him to make the right decisions.
