I hope this type of content is allowed, because I have a true story that some of you might find amusing/inspiring: Me (white, shy beta type) and my ex-gf (also white, cute short goth girl with big tits) had been together for 3 years already. I was her first, but had never managed to make her cum during all that time. Still, I was under the impression that the relationship went really well and that we were both happy.

We went to a concert one night and met an asian man, a friend of a friend. He was a bit shorter than me but much more confident, more social and better looking overall. My gf immediately developed a liking for him and started chatting him up. I first didn't think much of it as she was an outgoing person who liked making new friends and did this type of thing often. When we were about to head out to an afterparty at a friends place though, she made an effort to find that guy and invite him as well, which rang first alarm bells. When we were there she was already tipsy and spent basically the whole night chatting and almost flirting with him in front of everyone while completely ignoring my presence and my efforts to join the conversation. When I asked her to go home a few hours later she told me very decidedly that she wanted to stay longer because of all the fun she was having and that she would come home the next day. I went home feeling obviously very worried but powerless to change things. I saw her the next day and things were as usual. However, only a week later she officially dumped me out of the blue and the next time I saw her (only a short while later) she was officially with the asian guy. In hindsight I'm pretty sure that they had fucked already that first night.

Well, I guess that makes me a literal mayocuck. I was obviously heartbroken but deep inside also a little turned on by how effortlessly he took her from me. I suspect it's why the AMWF fetish has been getting to me so much, since I discovered it.
