Did I tell you I brought a married friend to my brother's wedding?
Are you close friends with your married friend?
No. We are not going to be friends anymore just because of my brother's wedding.
It's not okay to go on a date with a married person, especially to someone's wedding. Instead, you should have brought a date that was single.
Probably right.
Did his wife know he accompanied you to the wedding? It's not a good look if he didn't.
