It's Been a Long Time

Today, i felt about 5x more worried about school then usual then two seconds later I felt a lot better. I haven't written anything creative in a while or on here so I figured I update. Nothings been going on just a lot of nonsense.
I'm going to ask your opinion after I explain whats going on...alright here it goes.

Boy(will be the name I call this person which i'm sure you can figure out who he really is fairly quickly since you know me.)

So boy and I hang out we end up drinking a little (i know terrible but I haven't done that in a while and I didn't want to seem like a party pooper) we go on the trolley to the baseball game. Pretty drunk we get to the park and I pay for our two tickets it had been his birthday and I hadn't seen him in a while so I thought it would be only fair to pay for the tickets... turns out they were 100 dollars but still no biggie for me. We head in, we sit down we slowly lose the buzz of the alcohol as the game progressively sucks more and more. This was the night that the Padres decided to start with a crappy pitcher and make us lose 10 to 1, anyways we get food we eat, we watch the game we laugh we enjoy eachothers company we leave early.
We take the trolley back to his car he had been saying most of the night that the alcohol was making him tired but I figured it being 9:30 would make him realize it was a little to early to just take me home. So when he asked how to get back I asked to where my place or his... a few minutes later he says "yeah lets just go to mine we can watch a movie." We get back to his place we flip through some channels we kiss and cuddle we nap in his bed we kiss and then we talk. I ask him if he's excited about leaving he says yeah, i ask if he's gunna miss me he says yeah. Later we talk about why we aren't together, i say i understand its because he's leaving he says thats one reason the other is because he's in love with his ex still.
OUCH. Like a rock being jabbed into my ear and twisted a few times, I had wished to never have heard this. So theres my question, what do i do?
Everyone else says move on pick someone else just forget about him, but i dont want to. I don't see a reason to, we are still friends he is still adorable and he is still ... him. this boy this guy this fool look at what he's turned me into.


btw this is such a girlie post, i feel like a nerd to ask but still. I just dont know what to do, how do i get him to focus on someone else not on her?
