<human>: Can you provide a brief overview of the text?

I've been with my GF for 10 years and I want to propose and get married.   However, over the past 10 years I've had 2 or 3 minor 'slipups'. 

These have largely been in form of some flirting on nights out. It usually consists of - a girl hitting on me, and me not doing anything to discourage it, and instead encouraging it.

I have never actually kissed, or slept with anyone else - but it's the fact that I didn't do anything to discourage these things happening (i.e. not instantly saying "i've got a girlfriend") makes me feel guilty and unfaithful.

There's no real excuse for why these incidents happen, they have only happened 2 or 3 times over the 10 years, and only when i've been blind drunk.  As I said, I know being drunk isn't excuse but I guess I lose control and the flattery / excitement takes over?

I feel like I need to wipe the slate clean and confess this stuff happened before I propose - but I keep tossing the idea of doing this around in my mind, thinking it will do more damage than good.  

On the one hand I want no secrets at all; and the guilt / anxiety is wearing me down.   On the other hand, I can't decide if it's actually selfish of me - and i'm only considering this to make myself feel better.

What do you think, Reddit?
