Here's a story for you

Not asking for advice because I know this is a terrible place for it, but...

So my woman, at one point she brought up sexual history earlier in our relationship. We said our number or whatnot, hers was um...substantially...higher. I wish I could say it was twice mine... not something you wanna hear but college was a while back for her and I have mostly been a serial monogamyst except for a couple years in college. But I had to ask, was anything like crazy like 3 somes? She said no, life goes on. Anyways, I marry this woman. She's really cool. incredible and I have actually trusted her she really seems like an honest person who couldn't keep a lie so she doesn't even try. If not for her fuckups years ago, she would have been snatched up by a much better, classier, wealthy man than myself for sure.

Anyways...so we're on our honeymoon... we start playing drinking games with some foreigners. One was categories/never have I ever. Well question is "never have i ever had a threesome". I notice out of the corner of my eye that her finger goes down, on the 4th question she was out and I KNOW one of the other answers was the real no for her. I'm pissed, I say abruptly but fairly composed "fuck you you're buying me a Maserati someday you bitch" in the heat of the moment cause she makes a lot of money, and that was it. We didn't fight, night goes on and we had a pretty good time.

Anyways, we're back at the hotel, i can't sleep and she can tell somethings wrong with me. I try to not go into it because I know I'll say something terrible and mean but she keeps prodding me so I proceed to say really mean shit to her..

First of all, she doesn't remember me asking her about a threesome when we were talking about history but I definitely did. Her story ends up being that the threesome was back in highschool, and by it she meant she made out with her girl friend while one of them (i dont remember, she probably would have said the other girl) goes on to have sex with this guy. I call her out because I thought she had a boyfriend all through HS and this guy wasn't that bf...idk tons of bull and that's whats worse.

really sucks, not a great time to find it out. I know I'm a lucky guy but I can't help feel like her story is a complete lie and if she lies about that, then what
