I've been trying to look for appropriate wording for my situation, but I can't find any.
I'm adopted and it was an open adoption, so I know my biological parents. They are married and our relationship is good. Most people know I'm adopted and my bioparents are also paying for part of the wedding, so I would like to mention them in the invitation.
My adoptive parents (who I just consider my parents because they did all the raising) are paying for quite a bit of my wedding and so is his mom. I'd really like to mention all of our parents by name including his dad who passed away. Is there a way to show that they are all hosting without making it look awkward? (i.e. it looking like my parents divorced)
We're having a casual wedding at a secular venue, so wording doesn't have to be very formal.
