Feelings for my ex coming back..?

[Michelle]

We broke up 15 days before our 1 year anniversary.
He broke up with me thinking I would beg him I guess.(towards the end, he'd been feeling like I didn't love him... And I thought I didn't).
But I didn't. Simply said fine.
So then I asked him for my jacket back a few says later.(my favorite jacket, he took it without telling me).
Anyway, for the past 18 daus, I'd been feeling fine. In fact, I've had my sights set on a few people.. But then I noticed he kept liking things from our mutual friends on facebook(particularly things me and him talked about, example the new halo 4 game coming out) and since yesterday, I've been missing him. A lot. But he's over 100 miles away and I don't want to chase the past.. But I really miss him so much..
What would you do?
