I'm the divorced mother of the groom. I wasn't asked about the invitation before they were printed. Not only didn't I get an invitation (I was told it must have gotten lost in the mail) but to my surprise I wasn't even listed. I was asked to to make the rehersal dinner, it will be for at least 20 people, I thought I would be at least on the invitation. I don't know if my ex is contributing anything to the wedding, if that matters.
