What would you do?

My husband and I have had many ups and downs; from babymomma drama to overactive invasive family members that won’t seem to let us grow as one. We have gone through a lot. He has a friend that called him babe through text message that is supposed to be a homegirl. I don’t see where they talked on the phone but I see where they said they have. I don’t want to assume anything, but I’m at the point that I don’t even want to question him. I don’t want to fight. What would you do?
