My boyfriend was acting weird. I invaded his privacy and went through his phone, and I found infidelity. Should I call her, tell him I know, or just say nothing? My boyfriend is a polyamorous. His friends call me "manipulative" and say that I "don't let" my boyfriend "be himself" because I told him that I preferred to be his only girlfriend. Can I ask him not to engage in relationships with other people or is it selfish?
