I find it interesting that the op can make a viscious personal attack and yet not feel the need to apologize.
I am not bitter or spiteful in the least. You are putting your own issues in here. I have already stated that I have never been cheated on in my life. You have absolutely no idea what my personal circumstances are...
I have not called anyone names or been malicious in any way. I sincerely find it highly doubtful that any man, single or married is going to want nothing more than to look at xmas decorations with two single women after midnight once the pub has closed. I find it more than reasonable for married men to have friendships with single or married women. I can even envision this scenario being completely innocent if this was a long-term friendship but it isn't.
The op asked for opinions. If she only wanted ones that agreed with her than she should have stipulated in the op.
