Input: Text: i've been with my gf for 6 years. yesterday me and a mate started talking about tinder while drinking. for a laugh i installed it. i swiped a few times left and right, and then i uninstalled it (i uninstalled it because i'm obviously not supposed to have tinder while in a relationship). of course a friend of my gf saw me on tinder the same night, and told my gf.  
i've fucked up so bad.   
i realise i should never have installed it in the first place, i realise she will never believe i installed it "just for laughs", hell i don't even know if you guys believe me. i feel like shit for making her feel like shit. i'd never cheat on her and i love her with all my heart. im fucking almost crying while writing this, because i know i fucked up so much.  
  
what the fuck should i do? do anyone here have a similiar experience? what would you do if you so installed tinder?  
i'm so sorry baby

update:  
op here, thanks for your concern guys. i'm trying to be a man about it, even though i'm not excactly sure how.  
she's pretty upset, and i'm having a hard time explaining what excactly was so fun about going on tinder (i mean, it wasn't really fun at all).  
i just want to figure out how to regain her trust quickly so she won't have to live with me feeling like she's letting herself down. i'll also talk to her friends and try to explain what was going through my mind.  
conclusion is, i wish i hadn't done it in the first place, but i think it will be ok.
