Is my trust with this girl broken?

I (28M) met a girl (24F) about a month ago, we hit it off immediately. We’ve been seeing each other almost every day, she’s stayed over, and it felt like it was going somewhere real.

Early on, I found out she was cheated on in her last relationship. Shortly after, she rebounded by being with a friend of a friend of mine casually. This was relatively recent, which bothered me since I’ve been intentional, but I moved past it because she framed it as a mistake while she was emotionally messed up from the breakup.

She told me she’d only been in one serious relationship and one casual situation last year. Any other guy wasn’t casual, but also never became official. Later, I found out she had a 5-year on/off thing with another guy. They said they loved each other, met families, etc. She doesn’t count it as a real relationship because it was toxic and she was younger, but I see that as a flat out lie. To make it worse, she went on a date with him about a month before we met to see if there was anything there. She says there wasn’t.. but clearly the idea of him being a parter made sense very recently.

She also hasn’t been 100% upfront about other parts of her past, chalked up to miscounting. She says none of the lying was malicious, just embarrassment, and that she’s being fully honest now and wants to fix things.

I do like her a lot, but now I feel like I’m questioning everything and I don’t want to end up second guessing or digging for more. I told her exactly that, but don’t know of a path to salvaging. If it is salvageable, how do you actually move forward without constantly overthinking?
