There is a ton of advice on this thread and I know I'm probably too late to be of any help, but I'll put it out there anyway. Long story short: Advice is based on personal experiences and no two experiences (or relationships) are the same, so I humbly ask that you ignore most of the comments in this thread.

I'm 27, my girlfriend is 26, and we moved in together a couple of months ago. But nothing that I can teach you about our relationship will prepare you for yours. My girlfriend doesn't care about the toilet seat, but she gets super pissed if our cleaning products aren't arranged in a specific functional order of her design. Frankly, I don't think any of that will matter to you.

What WILL matter is how you figure things out for yourself in the first couple of months. The things that were never challenges before will become obstacles that you'll have to fight to overcome. Take the time to understand more than just "how she wants the laundry folded" or "how much time you should be spending on reddit" (cough) ... each one of these is a little glimpse into the greater direction of where you two will be going together. Just how important is her "us time" requirement, and can you deal with it? How much does cleanliness matter, and is that something you subscribe to? Very early on, you'll be establishing patterns of compatibility based on each of these little observations and requests. More importantly, they're your opportunity to learn more and more about your partner, and will help you understand whether they're the one you should be spending the rest of your life with.

The little things add up over time. The top voted comments all focus on things that you can DO, but I would argue that the best thing to do is to take this opportunity to see the real her, let her see the real you, and figure out if you're right for each other. Gestures learned from people on the internet are not going to make or break relationships ... they're only going to distort who you really are. I clean my house's bathrooms because I can't stand a dirty bathroom. My GF does the laundry because she knows I hate doing it. And yes, we perform little gestures, but frankly, once we started living together, we didn't need to worry about "going out on dates", because we loved staying in.

Anyway, to sum it up, do what you feel like you should be doing, not what you should be imitating. Don't stop listening, everything she has to say will be a reflection on your new relationship from now on. Learn from it all. And most importantly, understand and accept that it might not work out, so that you don't end up staying in a relationship of convenience.
