Most Helpful Guy
Even though Christmas has past, have him and his mother over for New Years! It'll be fun and relaxing for everyone. Give your moms alone time so they can talk and get to know each other more. Usually when a parental figure says they'd like to meet the parental figure of the person you're dating - this means that they're trying to get a grasp on this person's upbringing. Your mom probably isn't trying to make a new best friend at this point. She's simply scoping out the moral value(s) instilled in the young man you've chosen to date. And who better to get this from than from another mom?
