One of my plates banged another dude after I told her I didn't love her. We both had a semi decent emotional connection

She came running back to me last night waterworks and everything. I'm debating whether I should next her or give her another chance.

I get the whole "It's your turn" bit, but my plates need to be committed to me entirely or else I just can't handle the jealousy.

What course of action do you guys think I should take?

She said "I'm willing to do anything I just need you in my life"
