I suspect my wife is cheating on me with my dad

Two years later, my mom got married to another man-a man I grew up to recognize as my real father. I told him, "I have a woman I want to marry." He said, "Bring her home. I can't wait to meet my in-law." I took Sabina home one weekend. My dad said, "You have taste. See what you've brought home?" I was happy that my parents were happy about my choice of a woman. My dad and my wife became very tight. When we got married, my wife visited my parents more often than she visited her own parents meanwhile, her parents lived closer to us than my parents. He said, "You're still home?" I answered, "I'm about to leave." He asked, "But why are you picking your wife's call? Is that what you do?" I laughed and said, "I picked because it was you." The next day, it was a text message, telling my wife to have a good night. A month ago, I brought WiFi home and connected everything in the house to the WiFi. My wife was having challenges connecting her phone so I picked the phone and set it up for her. The first message that came in was from my father; "Is he home yet or I should come back?" Meaning my father was here when I was away? I scrolled up to check the beginning of their chat for that day. My wife: "Yeah, he left some minutes ago."(9:15am). My father: "Great, I should be on my way soon.” My father: "Is he home yet or I should come back?". Why would my father come around only when I was away? Thinking of the whole thing makes me feel traumatized. If I ask my wife now, I know she'll deny everything and ask why I would think that of her. I can imagine what he would say, "Your wife? how can I stoop so low to sleep with the wife of someone I call a son?". Source | Summary
