Hi BrokenDad,
I feel that same way as everyone, I am sorry you are here and I am glad you found us.
The only question that matters is what do you want to do. There are two camps here, fix it or get out. I am in the latter but my experience isn't your experience.
Fistly, you are in shock, you shouldn't make any life decisions while in this state.
Secondly, you most likely have PTSD, you shouldn't make any life decisions while in this state.
Thirdly, It is totally up to you what you do.
We can advise you but all of our advice is relative to our situation.
You might decide to fix it, she might not want to.
You might decide to end it and she might want to fix it
You might decide ... you get the point.
If you think you can move past the lying and the cheating then figure out a plan to do it. You need therapy, you need support.
You are in the driver's seat, it's your life and you can decide which direction it can go.
Everyone here will tell you what they think you should and most of agree on many things.

We start to diverge at this point, but really all of us only care that you take care of yourself.
It sucks you have to go through this. You will cry and be angry and rage at the world.
Its all normal.
It's your choice on what you do but don't think you have to do it right now, you need to process all of this and figure out your shit.
Your world has been shattered and you have to start to rebuild it.
It takes time.
I will end it with this, cheaters lie, so whatever she tells you, multiple by 100 and that might be close to the truth but you won't ever truly know.
You can make her take a polygraph but those are only yes and no questions.
The only questions you need to answer are what do you want to do, and can you get past her cheating on you?
