I mucked up and need help

Soooo here’s some background:

My boyfriend of two years and I had a threesome with another woman whose way more experienced. Our first threesome. We had fun and agreed to stay in contact for more. As she is into BDSM and we are curious.

He tallied me into letting them fuck solo, as I “cheat on him all the time and he loves it, we thought I might as well as I enjoyed watching them. The past few days before hand, after the threesome, my boyfriend was crazy loving and affectionate.

WELL this guy promised to send pics, vids, and texts throughout it and tell me when they would. And I didn’t find out till after.

I find out the fuck lasted 2 hours, and he gave 20 mins of after care. He was crazy rough with her and she wore a sexy outfit for him. We have never done that. It’s always 20 mins then he leaves. What’s worse is he was incredibly cold to me yesterday, barely even giving details. I was and still am crazy anxious and scared because when I told him he could hurt me like her he was crazy hesitant and acted like he didn’t want to.

I know I fucked up letting them do it, but I thought it would all be okay... I really don’t know if it will be now though.
