Stage Five Clinger

Ok. Here's the deal. I have been dating this guy for the past couple months. About a week and a half ago we decided to make it FBO. Big step, right? I didn't think much would change, but boy was I wrong. Instead of hanging out whenever we had time, he wanted to start hanging out everyday. He is my boyfriend, so I should want the same, right?! Wrong. I have found myself not wanting to spend as much time with him. I didn't think that putting a title on this would turn it into such a stressful thing for me. Last night I was spending time with my sister and niece, and he told me he would "wait" until I had time for him. Really?! I forgot one little detail... He's 26. So here's the question. Am I in the wrong for telling him that I don't want to get serious very quickly? Because even after our conversation about getting on the same page, I still don't feel like we are seeing eye to eye. This dating stuff is too much to deal with.
