Just got a tip from a close friend who I hadn't seen in a while, that a current girl I was fucking along with others is currently dating someone. Then the words changed to " I don't know bout now but a while earlier this time span they dated "

You know the drill. Pretty girl is fucking me while she plays date and relationship with her beta?

Worse part is she didn't tell me a thing.

She acted like wants to commit to me but I went hard and let her while spinning one and two other plates here and there.

How should I proceed? Face her with it? Or ghost and leave to show my value?
