@cutiepattoti that’s a little bit of what it is, I’d say. I was the same way with my boyfriend when I was 17. But, as I grew up, I learned how to appreciate time without him.
I would say to communicate with him about this issue. It’ll help you feel more open with him and he will understand your feelings more. I also would, like I said, try to appreciate your time alone when it comes up on those weekends. Do self care or something fun! Hang out with a friend instead! Don’t sit and think about how it would be fun if he was there, because you do get plenty of time with him! It will help you in the long run.
