My Boyfriend!!

I have the best boyfriend in the world. He spoils me. Has a great job as a firefighter he loves. He takes me on dates and is always there for me. I just don't feel "it" at all. You know, the spark. I know that seems childish and I had been single a very long time before dating him but I just feel kind of sad and distant becaus I don't know if I'll ever get there. I know he's perfect but I just feel like I might be going down a path with someone who may no be a do or die all man for me. I want it to be him but, idk. Is it too soon to tell? I mean we have spent maybe 10 nights together and I feel comforatable and safe with him. I feel so sad when thinking of losing. Is this just my anxiety talking? Am I being that annoying crazy girl? Help!!!
