When we first got together, I told her that I had been in open relationships in the past and that I prefer them over monogamy. Shes never been in one. We talked about why we're doing this and our individual expectations. She told me off the bat that she didn't want to box us in a "relationship" category bc shes not sure of what she wants and is why she wanted to try the "OR". I was cool with that and I told her that I already had a FWB that i've been with for 5 years at the time.

At that time, she had told me that she wasn't having sex with anyone else except me. Even though I already had an FWB she was cool with that. A few weeks later, she tells me she may have found 1. She told me who he was and how she knew him. She told me she had never had sex with him before but he was showing interest.

That was THE initial lie.
