She confirmed to me there was an EA with one of my coworkers before she left. A couple years before, I found out she had been flirting with her exbf. Less than a week after moving out, she hooked up with a coworker from my pt job. A week after that, I found a used condom at her apartment on top of the trash can (she asked me to stay and watch S while she worked).
Currently, she has multiple A with multiple OM/OW. She is not in one steady A, but she confirmed more than 3, and likely quite a few more that she eluded to, but not confirmed.
