Is my mom too attached

My brother and I are in college, my second year and his fourth. I come home every weekend and him every other. And every weekend she balls her eyes out picking us up and dropping us off. I understand she misses us but we can't even stay weekends because she will guilt us into coming home, and If we wanna go back to college early she says we don't love her. Even my dad agrees she's too attached. What do you guys think?
