My friend (Male) bet me that he could seduce my partner (Male) and I took him up on it because my partner has been faithful to me from the start. So this last week I had to go out of town for work and my friend invited my partner to his place to watch movies.

Tonight I got to see the video my friend made of my partner getting naked and having s**. I had no idea he would do this and now I cannot trust him. I am going to admit the plan when I see him tomorrow and break off our relationship. The holiday is going to be sad but it’s my fault.
