Address Adultress 

When your spouse claims to not be having an affair. However, a wedding invitation is delivered to your home addressed to your spouse and some other random person's name on it. Not my name, but my address! What the hell?

My spouse is an Address Adultress as a wedding invitation was delivered to our home. My spouse's name was on it and some random person's name too. Not my name Buddy?
