Emotional boy problems!!! HELP!!!

Mariah • I`m a high school student and have high goals for myself. I want to go to NYU.
So my ex broke up with me on January 6, 2015 bc he was going far away to college and I was still in high school and had bad experiences with long distance relationships, so we didn't talk for awhile until May of 2015 we became friends again. But I was an on and off friendship bc my feelings were in the way, and it just hurts me so much. And when we started talking again in October 2015 and he's been ignoring me lately, and I was wondering do I tell him how I feel about him leaving me and then coming back into my life whenever he feels like it and how I hate that he does that to me. Or do I just ignore him and never talk to him again. I still do love him and I hate that I do and I hate that I cry over him all the time. I just need a little bit of some advice here on what to do. Thanks!
