Does my Grandmother hate me or want me to leave?

I am a twenty-one year old college student and I live with my grandparents while attending college. I have lived with them my whole life and think of them as my parents. Lately I've started to feel like my grandmother is constantly mad at me even when we haven't spoken that day or I haven't really done anything to her. I recently came back from a trip I took during spring break and she was already upset with me. She didn't want to hear about my time and tunes me out when I'm around. If moving out is the issue I have no problem with doing so and have a boyfriend I could easily live with once the semester is over. I really feel as though I'm not welcome in the place I've always called home.
