I am a single NM F who occassionally dates ENM married men for FWB. I have recently decided to separate sex from dating, so one FWB situation while dating/testing the waters with other men without sex. I chose this because I am a bit of a sex addict, and my last combined relationship ended very badly with him pretending to be emotionally invested but using me and multiple other women for sex without our prior knowledge. I prefer married guys as a rule because I there's no chance I'm going to get feels (and tbh the sex is always better).

I met "Todd" (married/ENM) a couple months ago online and really got along with him. I made sure to ask if I was approved by the wife "Margo" and he assured me I was. We met up last week finally and connection felt perfect; sex was GREAT (and being with a snipped guy for the first time in forever was a sexy comfort, and I was able to get off in a new position for the first time in forever. YAY!), we were on the same page with what we wanted, had great conversations between sessions, and he made me so comfortable that with gentle conversational prodding I opened up about some light trauma issues I've experienced, that I've never told anyone other than a therapist (not a full trauma dump, he got bare minimum). He also admitted Margo was dealing with some jealousy over him meeting me and he'd have to face her interrogation when he got home; despite her forcing ENM into their lives and having multiple partners herself, she apparently doesn't think she should have to share Todd.

A few days later, I get a "thanks but Margo is mad so we can't do this again" message because Margo no longer approves. To top it off he unfriended me on snapchat before I could respond to wish him well and urge them to communicate better before they continue with the lifestyle. I wasn't upset to begin with, but as time has wore on I've become stuck with a jumble of emotions and internal questions that keep nagging. I feel like I have done something wrong when I know I didn't. Their lack of communication has left me as collateral damage to their marital strife, when my whole goal for this was just to have fun and not bring intimacy issues into my dating life; now I don't know what to do. How can you force (because she leveraged their marriage and kids and threatened divorce if he didn't go along with it) the lifestyle into your marriage, have multiple partners, then be jealous and not expect your husband to also seek out a FWB? I know I shouldn't have a huge problem replacing him, but this whole experience has now left a sour taste in my mouth and I'm surprisingly upset. I could have lived without the sex (though it was fantastic) and just kept him as a friend, because I don't have many friends and it was nice to confide in someone that didn't have an ulterior motive.

Thoughts? Am I overthinking this? Am I in the wrong? Should I have done something different?
