Friends husband told me he wanted to kiss me

A group of school Moms and their husbands went out on the weekend. We all ended up back at one of the couples house drinking. My Mom friend left at around 1:30 to go home to the kids and her husband stayed. My husband was sitting on the couch and I went to the kitchen for a drink. My friends husband followed me and told me that he really wants to kiss me. He was very drunk so I just said “oh I know, let’s go back to the party” and kind of ushered him back inside.

Once back inside, in front of my husband etc he was trying to dance with me a lot. He kept staring at me and then also looking sad when I wasn’t giving him attention. My husband was just chilling and doesn’t care about this stuff as he trusts me.

I saw the friends husband last night as he is the coach of my son’s football team. He completely blanked me and just ignored me when I was standing right there.

Why is he being so rude to me? I literally did nothing wrong!
