What questions should you ask yourself before moving in with a partner?

If things continue to go well, I may move in with my partner in August. What conversations should we have together beforehand to figure out if this is a good idea? I am definitely willing and capable of living alone/with a roommate. For reference, I am 21F and he is 23M. I am moving out of my parents house this summer and figured that it may be a natural transition.
