So many red flag warnings: Do not pass go, do not collect $200, and especially do not drop $2k on a ring to make this girl your fiancee.
If this is the same chick who you posted about a month or so ago, please, get out while you can. The chances are high that she is a serial liar and cheater and it's a guarantee that she's emotionally unstable. message me and I'll gladly give you my in-depth analysis that led to my answer above.
I'm sorry. Good luck, Sgt...

Try to talk it out. She SOUNDS loyal for telling you about this, instead of keeping it a secret. It's a good thing.
But suddenly accusing you, that's just weird.
Defend yourself, cause you have nothing to hide... prove it.
