Should I tell my girlfriend I kissed another girl whilst drunk?

So you're justifying his unfaithfulness with the reason: "She's probably done it herself."

If you can't see how warped your way of thinking is then I feel sorry for you. You're the type of people who give good guys a bad rep.

As a girl, I would much rather be told by my boyfriend rather than finding out from someone else.

Basically, a few months back I was on a night out and I kissed a girl. Nothing else came of it, I walked away and didn't see her again. I was pretty drunk, which is no excuse really, and I've felt awful since whenever I think about it. I've been with my girlfriend for over 2 years now, she lives in the same town as me and we go to Uni at the same place. We've not had any trouble with either of us cheating before, but I admit I've felt attracted to other girls but not done anything about it (also whilst I'm drunk). Is this a sign I don't love my girlfriend as much as I think I do? Should I tell her about the kiss and hope that she knows it meant nothing, or should I keep it quiet and hope the couple of mates that know about it won't ever tell her either?

I'll dumb it down for you: your way of thinking is warped and it make decent guys [who don't think in such a sick way] look bad. I never suggested you were a good guy to begin with. Comprende?

I'm having to deal Withyham exact issue right now.
Kissed a random girl at a club.

Got a guilty conscious. Have always told her everything because lies and secrets ruin a relationship... But I'm scared telling her will end the relationship or make her doubt my loyalty.

Just realised this thread is two years old. What?

it's funny how all these dummies point out telling her would ruin the relationship as if kissing the other chick wasn't what already ruined it. The reality is, even if she knows the truth or not, he still didn't think much enough of his girlfriend to just not do it in the first place. We're all going to pretend like oh, it happened in 1.5 seconds, I had no time to back TF away from her. Unless she literally fell on his lips, he sat there and let things build up until he got to where he is, wondering how not to screw up what he chose to risk in the first place. Let's be real, you don't need to be perfect or a genius or sober to not cheat.
