Hi guys - long time lurker, never posted until now. Just discovered proof that my long time gf cheated on me recently and lied about it to me. Im not close to being fully RP so looking for the best way to respond to this.

She is de facto staying with me so contact is unavoidable. I’m wondering whether I should confront her or just pretend I don’t know - what’s the best choice of options for me?

This is a bit frazzled, apologies
