Is it normal if now he likes me?

Why do people have to be so complicated? I used to this guy who is now my friend. We were talking and we were loyal to each other but never made it official because we lived apart and were busy taking care of our own stuff. However, there were times of course where being serious felt like a good thing to turn to. But it never worked cause of schedules on top of other things. Eventually we faded but now were just friends, hanging out with other groups of friends. This has all happened within two years. I feel way better than I thought I would. I an a lot more fun like the way he met me. We're getting along like we did when we first met. Deep inside I still love him and I know I always will but it just didn't work out. For him, he's a little more closed off but he did like me very much. And now, he wants to be with me again. He's been flirting with me and I do enjoy it of course but Im like okay now you want me again?? He'll text saying things he used to tell me when we were talking. Im not saying I don't like it because Im enjoying it while its happening, I mean I miss it. But its like why couldn't you be like this when we were seeing each other? Its kind of like that whole "people like the chase." I guess since hes only seen the fun and happier side of me recently as friends, it reminded him why he started liking me in the first place. Now he's all into it again but I'm here like, should I talk and see him again? now that I learned what to do and what not to do from the last time we talked like that? or should i stay away for now until he tells me he wants to talk to me? But knowing him, hes not gonna take the initiation to talk again. I would have to ask him "do you ever think we'll be together like we were before?" And then he'll answer which Im not sure what it would be. He could say "yes but not right now" or "yeah I don't see why" and go from there. He really indecisive if you can't tell. I havent had another interest like him since him and like I said, I still love him so I think I would go along with it.
