I really like him should i just go for it?

There's this guy I really like... we hooked up before but that was a while back... school started and I got really busy so we kinda stop talkin for awhile... we still talk but not as much we use to hang out alot too... but of course my busy schedule kinda holdin me up... now i got things goin smoothly so i have some free time... ne who... i really miss him... and i was thinkin bout callin him up and hanging out with him again... I really like him alot and I miss him... :-( Should I call him up and see where things go? What would you do?
