What would you’ve done in my situation?

I like a girl who likes me back as well and we do have a pretty decent chemistry, I came across her via social media and we started talking and its like I feel good whenever i talk to her. so as time went by I started liking her and she confessed she liked me back too. Now recently i got to know from her that she has been in 3 relationships previously, and that she isn’t a virgin and she went on to say that she slept with the guy as they thought they were going to marry each other and she also said that she has also slept with women too. This literally made me feel like my heart shatter into several pieces cause I have never indulged myself into sex at all. I have been in two relationships as well but since I am from a very strict family I could never imagine myself doing all that as firstly I rarely met the two women I was with maybe once in a month at max and also I never had sex or anything near that area as I would never be able to live with that thought, cause for me it matters that I save myself from that and save it for when the time is right. Now this thought of her that she has slept with someone earlier and even with women doesn’t sit right with me. Its eating me up idk why. Is it wrong that i think this way? Should i continue talking to her? Because i do want to marry her, given that we are in mid 20s, but this makes so much more difficult for me idk why, for her she said it doesn’t matter as it was her past and she wants me to be the present and future. What should i do? Advice greatly appreciated!
