I wouldn’t stress about it too much! My freshman roommate and I didn’t talk much before move ins and we were also both awful texters lol. We ended up being BEST FRIENDS, lived together all four years of college, and still hang out now even though it’s been a year since we graduated and we live in different cities!!
that def does suck but I would try not to take it too personally some people don't really like being friends with their roommates, not because they dislike them but bc it can make it more stressful to exist in their personal space as they feel like they always need to be on obviously idk your situation but just trying to offer a possible perspective
