Your girlfriend is a twit and a moron

If you get married to this woman, wait a couple years then do the same to her for pay back ;p

Technically, if you get kissed by someone non-consentially, it's a form of rape and should be reported.

Just teller that you remember how she kisses you.

I swear to God, not all women are that crazy. ALSO, slapping is RARELY acceptable, certainly not under those circumstances! I would end the relationship, she sounds amazingly needy, abusive and obviously has low self-esteem.

I would think having to confirm her identity first is a greater sign of cheating

That has to be some kind of psychological disease. "How dare you potentially make a mistake that has a 0.0001% chance of occurring"

Your girlfriend is a nutcase

Some people have the stupidest beliefs

She just ruined a totally romantic moment for you guys.
