Getting over your first love?

I'm only 16, and I'm sure many of you will say I don't know what love is, but I've liked the same guy since the 2nd grade. He was my first boyfriend and first kiss and we've dated off and on up until 8th grade.. I've had a lot of other boyfriends since then and were still very close friends but the feelings never go away.. I could go months with out seeing/talking to him and feel like I've moved on but as soon as I take one look at him everything comes flooding back.. Is moving on hopeless? Because it feels like it .
