should I stay or should I leave?

So, ive been seeing this awesome guy since thanksgiving. We havent put a label on our relationship or anything. And that's fine with me. I really like him and I jave really strong feelings for him. Although I can see us spending some serious years together. I dont know if I love him. I know love dosent happen over night. But I just got out of a 6 year relationship. He came out of an engagement. We've been sleeping together. I bascily live spend every night together. We are even planing a trip to AZ in a few months. so i guess my queation/issue is if I dont love him should I leave? he treats me amazingly and i really like him. Some times I feel like I could be falling for him. Other days I have no idea what I'm doing. How long do I wait? Im happy and im not putting a time frame on my relationship . Im happy. I just not sure if im wasting his time.
