<human>: Condense the text into a few key points

Sorry. You will probably be disappointed that there's pretty much zero detail here, because the details are VERY specific and if I really put any details, honestly if ANYONE who knew me saw it they'd probably know it was me.

The only thing I'll say is that almost two years ago I had a really bad feeling something happened between my girlfriend and another guy. She didn't seem like the type at ALL, and I still question my sanity for questioning HER, but the things that tipped me off seem pretty obvious. At the very least they were incredibly disrespectful to our relationship. There's just too much evidence that SOMETHING happened. It doesn't make sense. You get that sinking feeling in your stomach, you know? Like, a few too many things that just, knowing your girlfriend's personality, don't make sense.

I am going to find out. I've spend two years planning this. It's fucking foolproof. It won't happen for a while but I will update when it does. I just needed to let this out.

**This will be huge for me**. Because I am either being insecure, and making something out of nothing, or my girlfriend, who seemed like one of THE most trust worthy people I've ever met, cheated. 

I'm wondering what I could do during the mean time to keep myself busy. I know that this will all be solved in a few months but for right now it's torture. The thoughts are in my head of my naked GF and this guy having sex in all sorts of different positions. Are gut feelings normally right? How do I tell if its a gut feeling or just insecurity?
<bot>: I think that my girlfriend may or may not have cheated on me almost two years ago, but I am going to find out.
