I've NC as don't want this associating with my other username.
I went for a coffee yesterday and bumped into DH best friend. I was sat on my own at first and there was nowhere else to sit so said he could sit with me.
We got talking and he said he's been wanting to get me on my own for a while. He mentioned an incident a few years ago where he told me he loves me and I should leave DH (xmas party at our house he was drunk at the time and I just laughed it off as he's never mentioned it since and neither have I...I assumed it was drunk talking and he couldn't remember) I didn't say anything to DH as didn't feel it was worth mentioning. DH and I are happily married and DH friend was bestman at our wedding and another friend who is part of the same group said not worth saying anything as he doesn't mean it he was so drunk etc.
We went out as a group a lot (before Covid) DH friend is now single and has been since lockdown. It became awkward as he said he remembers that night well and meant every word. I was bit embarrassed and just said well nothing is going to happen so get that out of your head and stop being silly! He then started going on about how DH takes advantage of me and how unhappy we look and he wouldn't let things just be...he would make me so happy and loved. I honestly was speechless for the first time in my life.
DH friend is very generous and earns a lot more than us...I would love to earn more so we could do more but it's not going to happen and just think we're lucky to still have jobs etc and we're ok financially, will be able to go on a nicer holiday next year due to saving over the pandemic, we've done bits on the house...so all good.
I am annoyed as I don't think DH takes advantage at all and racking my brains as to what the hell he meant. My friend has said she's thought something for a while mainly since the party he likes me due to the way he looks at me etc and there is a photo from our wedding that her friend thought he was the groom. She said she noticed a few weeks ago when we had people over for the first time and he couldn't stop staring etc.
I don't know if it's because we were there for him when he broke up with his partner and he's just blurred the kindness.
I've told DH about the xmas party and the cafe and he says he wants to punch his lights out...what on earth do I do now? I love the friendship group and we've been through a lot together as a group but this is just so awkward and I know it's going to get messy with the DHs 
my DH was on the phone to his other best man going barmy. Other friend has said he knew about it but didn't want to get involved.
AIBU to ask him just calm it down. I get he's hopping mad and I would be too but breaking a group of friends up over something I have no intention of pursuing isn't worth it. I've said that he is not to be invited to anything that we are doing but we can't control what others do.
