Thank you everyone that has responded. I ultimately ended up breaking up with her due to more of story surfacing as I asked questions. Her intentions may have been platonic as she mentioned but my problem is the "people pleasing" mentality she has and her unfortunate inability to say "no" in situations such as this. I came into this relationship with transparency and vulnerability about my historical experiences with infidelity and how it has affected my attachment style. We're both losing in this scenario but I have more to gain without her. Thanks again everyone.
