I want to be with her but I might still be in love with my ex...help..will give all points for best answer?

So,i'm a senior and I play sports,i've had lots of and I can be a little obnoxious sometimes.I met this girl and I like totally fell for her instantly,she's hot,smart,funny and lots of other great stuff. I'm usually only drawn in my looks most of the time but I didn't notice that in her,so we got to know each other and her friends tell me she really likes me,I'm supper happy about this because I like her,so we tried some stuff which i'll tell you about further down in the paragraph but my biggest problem is my ex-girlfriend.Me and her dated for about 2 and a half years,we were in love,seriously in love,after we broke up we were on and off and every time we see eachother it's like in the movies when an old couple sees each other and then they head to the nearest broom or room and have really great .Me and her do that,accept not in a closet but i'll see her and I remember what we had and then we head ot her or my house and have the best in the world like we used to,do I still love her? I think I kind of do.The girl I like now is a virgin and when we tried to have she couldn't even take the tip of my d***.I fingered her and lick** her Pu***,but she can't take me,so we tried it again after i loosened her up and she still couldn't take it,and she said just try to push me down on it slowly to make it hurt less,so I did and she like almost cried and she is still a virgin didn't pop her cherry.I don't know if I should pursue her or my ex.
