I'd have a problem doing so by myself. But in a group setting I wouldn't and DH wouldn't.
Heck, DH had no problem with me meeting with an ex-boyfriend for lunch after we got married. Ex-boyfriend didn't know I'd gotten married and wanted to "discuss old times and new." DH didn't want me to let him know I was married so that we could see what ex's intentions were. Unfortunately, I couldn't pull that off. I kept saying "we" over the phone until "ex" asked who "we" was so I told him. LOL
