?

So I meet this girl when I was 14 and she was 17, we really started bonding during the summer and it was going really well for a while I asked her out once and she said no I'm pretty sure it had something to do with the age difference among other things now 2 years later (I'm turning 16 and she's turning 19) shes had various boy friends throughout this time, we tell each other "I love u" and and we would like cuddle when we first meet but now she comes to my house at all hours of the night 11-3am ect.. And she has told me that when we hug I should grab her butt and thats what started the touching, now I've grabbed her boobs b4 as well as constantly grabbing her butt also we have kissed once it was a peck and I'm pretty sure we've never kissed again cause I to scared to initiate anything else, the thing is she has a boy friend but she lets me grab her and I'm pretty sure she like it she's also told me that when we get older shed marry me? I'm confused does she like me?I Think I love her
