Do I have the right to confront her?

I'll keep this brief. Since returning from winter break, my girlfriend has become quite distant. When I ask her about it, she says she's just busy with sorority recruitment and classes. I remind her that during my own busy times—balancing athletics, six classes, and two jobs—I still made her a priority and went the extra mile. Despite us living just five minutes apart, she hasn't made any effort to see me, which really hurts. I feel it's reasonable to expect the same dedication from her. Every time I bring up her lack of effort, she responds, "We all handle stress differently, and you need to respect that." Lately, I've been focusing on myself and doing what brings me joy, but I can't shake the feeling that I'm being gaslighted. I'll give it a few more weeks to see if things change, but if not, I believe it's time for us to have a serious discussion about our future. What are your thoughts?
