My family and I have always been close. I’ve had a really good relationship with my parents, especially my dad. He’s always been supportive of me, especially when I got my gf at the time (now wife) pregnant when she was 17 and I was 20. He would help with shelter, food, clothing and other basic needs. We lived with him and my bed-ridden, disabled mom for the first few years of daughters life while I worked and saved money for our own place. So my wife would often be home alone with our daughter and my mom. My dad would work 12 hour or longer shifts early morning to late evening. I started working night shifts to earn more money about a year into this.

After a few months I noticed that my wife and dad were getting very close with each other. They joked around a lot and hung out. I didn’t think much of it other than “great, they’re friends” and left it at that. After a couple of years doing graveyard, I had finally saved enough money for a down payment on a house and was making enough to support our family on our own. We moved out. My wife insisted that she would visit my parents almost daily. I was fine with this as my daughters grandparents were an important part of her life.

Fast forward a couple of more years and I get to work one night. After a couple of hours the floor manager sends some people home because we all had been working lots of overtime and wanted to save on overtime pay, one was me. I’m excited because I get to spend time with my family. It was about my daughters bedtime so I didn’t call ahead to let my wife know the good news.

I get to my parents house and go inside. It’s dark so I assume everyone is asleep. I walk through the kitchen (the main entrance) and into the living room, and that’s where I find my wife and father.... embraced with each other.

After a few minutes of WTFing, I leave. My wife tries to call me but I couldn’t talk to her. The next day she comes home and we talk. Says she was just lonely at nights because I worked all of the time and my dad was there to help her. I have no idea what to say or think. The two people that I loved more than anything (other than my daughter) had betrayed me. I took some time off of work and kept my daughter with me while my wife stayed at my parents. My dad has tried to call me but I can’t talk to him. I have no idea if my mom knows (probably not).

I have no idea what to do. I’m assuming a divorce but what my relationship with dad? I’m guessing that’s fucked forever.
