I feel jealous and I’m wrong

I found this awesome girl and she loves me crazy. We share same Christian values and I am constantly teaching her more. We live together, we are feeling well together. I found out about her sexual past (she told me) and it greatly irritated me. She was emotionally blackmailed to have sex or they threatened to leave her. This happened with a few men (both the guys and the girl were young, around 20 or less) but she told me it was daily. I got that feeling of disgust and well I think you know what it feels like. Now, me, someone who found Christ and cast according to His word found myself in a place of jealousy and hatred for something which happened back then. She is changed now but that past “stained” her image in my eyes. Still, even tho it made me feel awful I am not giving up on the girl I prayed for and didn’t look for, but instead met when the time was right. Has anyone been through that? I need some kind words to help me accept this. It’s about me. I didn’t get to enjoy an amazing sexual life and I feel jealous. I’m also greatful for that because maybe it would have strayed me from God. Now I agreed to never engage in any sexual act anymore unless I’m married, something which got me very close to God. She also agrees with this and it was one of the first things we told each other. How can I ease my mind? I’m a very proficient overthinker and I’m often trapping myself in my mind. Any advice is welcome. Preferably from people who experienced such situation. Stay blessed
