Girlfriend used to be a slut. Should I leave her?

I've been with my girlfriend for about 18 months now and I just found out that she was a slut before we met. When she was in college she had several one night stands and was with at least 6 guys... probably more. I was aware that she had one other boyfriends before me and I could deal with that but the idea that she has had casual sex with 6+ other guys makes me sick. We've had a lot of fun together and I love her very much but I think I might be better to just end our relationship now before things get more serious.

I care about her a lot but I am pretty grossed out by this if I'm being honest. I don't want to hurt her feelings so if I do break up with her I think I'm better to lie to her about the reason. Do you think that I should just end things now? I'm just looking for some advice. Thanks
Leave her
Stay with her
