I 22M am really struggling coming to terms with my partner 29F past.

We have been together for 10 months now She’s had 8 boyfriends in the past and has had casual hookups aswell totaling to 30 partners, our relationship is great and we really love each other we also live together. I’m just really struggling coming to terms with this and I don’t know if it will ever get better I’m contemplating ending it for my mental well being. On my side I do not have a promiscuous past she’s practically the first person iv been with. I don’t know what to do. She wants to build a future together and I’m in the situation of do I fully commit to this or not. Does this situation get better with time? Or will I always be bothered by this part of her?
