I also looked at your other thread. It seems that you have been going home a lot. I have a few thoughts on that.
Going home too much when you first go to college isn’t a great way to settle into college life. It’s too easy. Part of growing up is learning how to cope on your own, figuring out what works for you, socially, educationally, and mentally. It might be that going home means you don’t have to worry about the stresses of college life. It’s comfortable, it’s easy, it’s familiar. But you aren’t really doing yourself any favors by choosing the easy option.
If you are not around campus on weekends, when students are relaxing and hanging out, you are missing opportunities to get to know other people on a deeper level. When everyone else is forging new relationships and figuring out things on their own, you may not have been there to be part of that. Be honest and ask yourself if it’s possible that your roommate wasn’t wild about being alone, and in your absence, she found other friends.
None of this is to lay blame on you. It’s just to help you realize that maybe it’s a good idea to see the flip side of your situation. Best of luck going forward.
