What should I do?

It’s this guy I met in March and we’ve been hanging out a lot lately. He lives 3 hours away from me and he’s drove to see me twice so far. We talk every night, he tells me how beautiful I am, takes me on dates, plans future dates and just makes me feel good overall. We’ve had sex plenty of times and it’s great. The problem is he’s not clear about if he wants to be with me or not. He says he’s a go with the flow type of person. I asked him how did he feel about me and he said, “ you know how some people are so aggravating and you can’t stand to be around them, you’re definitely not that.” He also said he can see why other guys would want to be in relationship with me. I was so confused because I don’t feel like that tells me exactly how HE FEELS? I don’t know, he did tell me that sometimes it’s hard for him to open up but I just don’t want to waste my time with a situationship!
