is this so called "friend"

It's only natural to feel disappointed or upset when you feel like a friendship is fading away. However, it's important to keep in mind that everyone has their own life and priorities, and being busy doesn't necessarily mean that they don't want to stay in touch with you. It's also possible that they may not realize that they haven't been staying in touch as much as they used to.

In terms of whether you should wait for your friends to contact you instead of contacting them, it really depends on your personal preference. If you feel that you're always the one making the effort to stay in touch and you'd like to see some reciprocity, you could consider letting your friends know how you feel and see if they make an effort to reach out more often. On the other hand, if you don't mind initiating contact and you enjoy staying in touch with your friends, then there's nothing wrong with reaching out to them first. It's important to remember that friendships are a two-way street, and it's always good to communicate openly and honestly with your friends about how you feel.
