So I am M18 and I've had this friend for about 8 years. (We met in about 4th grade) We connected very well and always hung out. He's been that one best friend for me, but not only is he great, his mom is too. my friend is just with his mom, and they just live without any siblings or anything. When I was about 13, I started to realize how attractive his mom was(She's in her mid 30:s right now) . I would always have my eye on her whenever we hung out. Anyways, fast forward to now, one normal day when I was with my best friend, at his house , but he had to leave urgently for a doctor's appointment I think it was. Now this left us with just me and the friends mom, and we ended up talking. However, this talking got deeper and deeper, and we were eventually getting physical. After about an hour we enjoyed our selves, just before my friend got back. I still have t told him about it yet.. AITA for not telling him and hooking up with his mom? He already knows that I think she is attractive, but I don't think he would assume I'd ever go that far...
