So the other night we're out and she used my phone for uber or some shit and found that I've been seeing lots of chicks on tinder - question is do I just own it - I didn't even say I'm sorry I just said that I didn't wanna define ourselves lol - I don't wanna drop her but she's pissed obviously.

What is the best way to handle? I've basically just ignored her each time she brings it up. How do I know when or if to comfort?
