Anyone get cold feet, back out then regret it?

So a long time ago when my then gf found out about my interest in cuckolding (more than 7 years ago now), she was open to the idea of it as she had a thing for a certain type of guys she had never experienced and also had very limited sexual experience (only one guy prior to me).

She found one guy online who she was really into and since I hadn’t done this before, I got too much in my head and worried that she’d leave me as she was only talking about the guy all day and night. They had a date booked and she was going to go to his place and the way she was acting, she had never been like this around me before. Because of my own stupidity and fear of her leaving me, I backed out and called it off. She was pissed at me and didn’t speak to me for days after this.

I think maybe a year on I tried to get it going again but we couldn’t find a guy she liked that wasn’t flakey so it fizzled out and I’ve never been able to start it again since.

Present day, I’m still really into this but she very rarely brings it up (said she’s still sometimes curious of trying a big dick as I’m only 4.5” long and 4” girth).

So the question is, has anyone had this same situation where they backed out and regret it as they never got the chance to this day? Or did people have luck after a very long period.
