It’s early in the year and you’re still learning about each other. Mend fences and continue to go to dinner together, go study together, shop for room stuff, whatever, but now you know not to go to parties together. There will be other things you learn too, but make a note of this one and keep going. It’s a long year, but that can be positive or negative depending on how you handle this and your attitude going forward. Not everyone is the same, but you can be different and still be good roommates.
