So I was at a NYE party last night. When the clock struck midnight, a girl came up to me and grabbed me and started making out with me. It totally surprised me and I was hammered so I went with it and kissed her back. Her friend ended up coming over and kissing me as well.

But I feel really bad about the fact and I'm not sure if I should tell my girlfriend about it.

I really value honesty but at the same time I feel like this is kind of insignificant and would just cause problems.

I'd really appreciate any advice.

Also hope everyone had a good new years!
