That's messed up, I don't understand why women are so unfaithful seriously if you don't want to be with someone intamitly the leave them I'm sorry man.

man I hope she was joking. you deserve someone who is faithful.

At least you caught her, now leave her with nothing and move on to someone who wont take you for granted.

If I was you I would've kept playing along up to the part where y'all meet. That way you get to see the look on her face as she tries to "explain". If you are lucky, she is just messing with ya. If she really is cheating, tell her to her face that you hope she lives forever so she can watch everyone she loves die. Ha

misunderstanding maybe?

Plot twist: she thought she was having an awkward conversation with a relative

I would have replied back with I want a divorce

You realise of course that she may be kidding around just as much as you were and simply be better at it than you!

sorry bro, good luck

Dump her immediately, sorry OP..
