Bf lied about being a virgin. His body count is 50+ I am going insane.

Last year I met this wonderful gentleman. I'm waiting for marriage and he told me he's also waiting for the right girl. Eventually he convinced me to do it saying things like I'm his one and only and now or later makes no difference bc he's gonna propose after college. I hate myself for giving my virginity to a disgusting liar. I later find out through his drunk hb that in his freshman year he joined a frat and did almost every girl at their parties. I thought he was joking until my bf starts throwing hands. Then I asked him if it was true, he looked so guilty, started crying and begged me to stay. I thought he was the one for me but he just told me he actually slept with over 50 different women and had an ex in highschool he did it over 100 times with. Do I break up with him? I love this man but he tricked me into losing my virginity and he lied to me.
