Do you consider this child molestation?

When I was 7 years old my 15 year old cousin lured me into a tent a shooed my brother away using all that " your special" crap. Once I was alone inside the tent he told me that if I were to take my clothes off for him that I would not get hurt. But I didn't want to and I was really scared so I sad no and briskly started walking out if the tent, I would have ran but I did not want him to know that I was scared. But as I was leaving he grabbed my ankles and I fell face down on the floor, the only things I had outside of the tent were my hands which I was using to claw at the grass outside in an effort to save myself. But I was to scared to scream or even speak at this point and so he began to take my pants and underwear off and he turned me on my side cause he couldn't see certain things from the back, but he didn't touch it. Then he let me go and I tried to tell my grandma put she blew me off. About a year later he spends the night in a van outside of my house and in the middle of the night comes into my bedroom, he tells me he has important things to tell me and that I need to follow him into the bathroom. It's a jack and Jill bathroom so he locks both doors but my lock is broken and I tell him that he says he doesn't care it makes him feel safer having it locked. Then he tells me if u show me yours I'll show you mine. I say no and start walking out. He stops me and then it goes blank, I don't remember anything after that point except for a long time after everything was done he came back in my room and told me not to tell anyone and made me promise. And then the last time I wake up one of the nights that he's sleeping over and he is over my bed and my covers are off and he's unbuttoning my pants :,( and when I was 14 I told my mom and a cop and he said there was nothing he could do because of a lack of evidence and that it wouldn't be considered molestation or any abuse because he didn't touch me. And my mom didn't believe me and kept asking me if I was sure. :(
