I guess I know the answer, I just need to hear it from someone else.

Going exclusive is the next step towards being serious, if not making things serious at that step. It sounds like he does really care for you, and wants to be with you only. I can understand not wanting to make things "official." Doing that means it's not just a casual thing anymore, you are taking steps toward a LTR and possibly a life together. That's a serious thing to consider and it takes a lot of work to get through that. He is most likely very open to that and maybe even planning on that happening, but he is just not ready to make it a for sure thing yet. The reasons for that can vary quite a bit.
The only problem I could see with waiting would be wondering "how long?" I would suggest having a serious talk with him about what kind of time frame you are looking at. Something from him to know that you would not just be waiting around for months and months with no decision or plan in sight. It could be that he wants just a little time, or maybe a few months, or even years. So I think it would be best to get some kind of answer like that from him so you are not just left hanging or wondering what is going on. Do let him know how you feel, that could help him move forward with this too. Good Luck!
