Not sure why I can’t post on this sub. Maybe the post is too long ? Hence this will be continued in comments
So bit of a back story – my gf from college (let’s call her N) and I have been together almost 10 years, and now we’re very happily married. While we were in college, N had a best friend (let’s call her M) . Before N and I started dating in college, I was friends with both N and M. I kind of had feelings for N but I also knew M was single and would readily date me if I asked her out. I knew she kind of liked me . There was always a sexual tension between M and I, but we never acted on it because she knew I had feelings for N, her best friend. Eventually, N and I started dating, and M also got a bf short after, and we’ve been steady with our respective partners.
