<human>: Can you give me the gist of the text in a nutshell?

I [22F] have been really good friends with my roommate in college [21F] for the last 4 years. We consider each other best friends (both said it unprovoked). We both don't have many other friends, just have both had a few relationships with guys that were far from serious. 

I had been respectful: only having him over late at night (I made sure we were very quiet), and mostly going to his place.

My friend has a guy (which she claims she doesn't want to date) over daily. She won't go to his parent's house. This is a week after she ended another relationship she apparently doesn't care about. 

Exams have begun and I have to live at the library while she spends time with her "friend". I am moving home permanently (9 hours away from her) in a week. 

I've tried to talk to her but can't get anywhere without prying (which I haven't). Am I overreacting, or is the friendship dead?
<bot>: My friend/roommate is choosing to spend time with a guy she "doesn't like" a week before I move far away.
