My dad (59M) sent me (27F) gay porn of himself.

Quick backstory- my dad (59M) and my mom (59F) were married for 27 years and abruptly divorced 4 years ago. He moved to a different city about 30 minutes away. He has had 2 roommates who are younger men.

About 3 months ago I (27f) made the discovery that my dad was gay with one of his (22M) younger tenants. I made this discovery on accident and I didn’t mention it to my dad, I am pretty sure he knows I know, though. At first, I was extremely shocked, but as long as my dad was happy I love and accept him and whoever he chooses to love.

Yesterday I received a video text from my dad. I am on vacation visiting my in-laws so I didn’t view it right away. When I sat down to look, it was a video of his roommate performing oral sex on him. My heart sank and I felt sick to my stomach. Obviously, no one wants to see their parent like this and it was deeply disturbing. I immediately called my brother (26M) who I had already told about my dad being gay. He said not to respond to the text so, I didn’t. About 40 minutes later I received a text from my dads saying “oh no forget you saw that.” I told him I already deleted it and I love him and I already knew he was in a relationship with his roommate. He brushed it off apologized and asked me how my day was going.

I just am just unsure where to go from here. I am not sure if I can ever have the same relationship with my dad and I’m worried things will be very uncomfortable between us going forward. My husband thinks he did it on purpose, which I do not believe was the case. My brother thinks it was extremely bizarre and was an accident. I am just very angry, I don’t want to be but, I am. I don’t understand how he could be so careless to send a message like that. Has anyone ever had a weird situation like this happen to them? How should I proceed going forward to maintain my relationship with my dad whom I love very much?
