My buddy ended up hooking up with my mom. I was not happy about it at all needless to say. It took time but I ended up deciding to just forgive them. My mom does not know I know and frankly I want to keep it that way. The problem is my friend always brings it up. He swears it was the alcohol and he will never do it again, but he seems to not be able to keep his fucking mouth shut about it. Comes up at weird time. What should I do? What is the psychology around this guy reminding me that he was with my mom? Is this some kind of an alpha thing or what? How can I get him to stop? I am worried our mutual friends will find out at some point.
