Yeah, it's normal. Some parents have a hard time accepting that their role is to raise the children and then shove them out of the nest and teach them to fly on their own. Doing things with friends is part of the college experience and it is your choice. You can tell your parents when you want to go home and visit.

My parents fought me so hard about establishing independence that the relationship was permanently damaged. They sabotaged me so that I couldn't go away to college my first year, so I found a way and ended up in a different state the next year without the resources to go home and visit, and they didn't want to invest in long-distance phone calls to keep in touch with me and I was barely surviving and couldn't afford to call them. It was before people had internet in their homes. I'm in my 40s now and grew up without having any family connection at all as an adult, which made me ripe for an abusive marriage with built in isolation. I still live two states away from my parents and we call once in a while but they don't visit and I can't afford to visit much. At least you are close enough that you can visit when you want to, and you do stay in touch. Tell them it could be much worse. Use my story if it helps. But you are at an age where it is normal to spend some time with your friends and have your own social circles, and you have a choice about when you visit your family.
