I desperately need some advice on the cucking relationship. I know its a bad idea to play with friends, but I did it and now regret it.

I spent the last few days at my friend's house. She's my best friend, and she was the first person I called at all the lowest moments in my life.

As we were catching up, I let slip that my new boyfriend is married and his wife approves (she set us up). My friend admitted to having the same fantasy and when her boyfriend arrived, she asked me if I wanted to play with him. I reluctantly said yes and I gave him a blowjob, which he enjoyed after realising it wasn't a trap.

The next morning, I was making breakfast in the kitchen and my friend came down and said she thought I should go and that she'd phoned a taxi to take me to the station.

I have tried to text and call her, but she hasn't replied. How can I repair my friendship?
