Husbands friend

My husband and I went out for st pattys day with a bunch of friends and had a great time. We totally needed a night away from our kids lol. However. One of his friends pulled me off to the side when my man went to the bathroom and said how I fucked up choosing him. Before I could ask why my husband was back. So whatever but now it's been on my mind what he meant. We NEVER had a history at all lol. I'm wondering if he knew about my husbands cheating and thinks I deserve better. Not too sure but it wouldn't have been the first clue. Anyway I told my husband and he seemed too unbothered and said "I know he's always had a thing for you." It's just bothering me too much now. Idk just venting a bit.
