My ex slept with other guys while on a break

So we broke up with no contact for like 6months, after those 6months i moved back to town and we bumped into eachother. Small talk lead to more talks, and a couple months later we hooked up again.

Now we are both thinking about being commited to eachother again but,

We have alot of deep rooted issues and horrible things we done to eachother. Wich i can actually get over with no problem and she aswell, but the one thing that really bugs me is when we where broken up she slept with 2 people. I asked a bit how the hookup wents and she said it was both a one night stand with some guy she already knew for a longer time just to try it. Wich raised my question, why only once if you already knew eachother and the sex was ok? Who didn't want to commit? What was going on? Does she lie about how much it happend to downplay it?

All of that really doesn't matter what matters is i can't look at her the same after knowing what has happend, i am still seeing her as of now but it just doesn't feel the same for me. I can't imagine myself living a happily ever after with her, knowing after meeting me she slept with other people. Like who wants to get old like that and settle down?

I be looking at my wife knowing what happend in our early years of dating, and all the bad horrible toxic behaviour i could just laugh off as immaturity or like haha silly us back in the day. But knowing myself i wouldn't be able to get over the fact some other dude was throbbing her and she enjoyed it, knowing i was in her life already. Even apart it doesn't matter to me, she shouldn't have done that.

I'm deeply conflicted because i know from my experience she is verry special and i could have had a happy life with her.

What would you do? How could you get over that? Would you?
