This is key. I think the question is not about whether you should move in together, but why you are in this relationship in the first place. It sounds like she basically annoys you after being too long together. That ain't right. You say you love her, but are you IN love with her? Or are you just putting up with her because you don't want to put in the energy of breaking up with her and finding someone else whom you DO love spending time with?

I mean that: Do you LOVE spending time with her? I don't mean, do you want to spend every second of your day with her, but do you TRULY look forward to being with her every day? Do you miss her presence, or do you look forward to getting rid of her after a set number of hours?

To be frank, it really sounds like you just want a girlfriend, to have a girlfriend... and one that doesn't expect you to grow up anytime soon. Which is fine and all, except that this isn't THAT girl. No offense to either of you, but you sound pretty incompatible at this point... certainly for living together, and perhaps in a relationship in general.
