<human>: Condense the text into a few key points

I've been with my GF for nearly 4 months and I really like her. We do not currently live together, but I spend a majority of my days with her, either sleeping at her place or mine. We have few arguments, although we do have disagreements with each other and petty grievances (we are both only children).

I am contemplating moving in with her next fall, mainly on pragmatic grounds. It would be mutually beneficial; we both would save money on rent, will be able to pool resources, have more total space, benefit from each of our offerings (her cooking / my cleaning + shared material benefits). Neither us of have ever lived with an SO and the thought of moving in together is both daunting and exciting. I am thinking optimistically and considering how much we could both grow from the experience -- how it would present challenges, makes us more responsible, prepare us for similar experiences later on in life.

I get there are drawbacks and risks associated with the move. We've only been together for a short-period of time. It is difficult to know at this point if we will want to jump on this idea in 4-6 months from now. Being only children and both very controlling, we will definitely have trouble sharing space, (e.g. I tend to be very clean, her very messy.) We both, to some degree, are limited in our adulthood experiences and problem-solving abilities -- We are both still undergrad students and will be next year. She is concerned that she won't have enough space.. that signing the lease would make it difficult to get out of the relationship (at least for a year) and would tie us down. She has poor benchmarks (previous experiences have taught her that she tires from BFs she spends a lot of time with). I argue we will be so busy with school and work (for me) that this won't be the case. That we already spend an incredible amount of time together, that this will not be unexplored terrain.

Can anyone offer their thoughts on living with a SO for the first time? What are the pro and cons? Given the specific detail I've provided you, can you offer any advice on whether or not it would be a good decision?
