Relationships go through transitions, and it's not healthy to resist them. You need to stay open to change and understand that just as you grow as a person, they do too. You want the best for your friends and loved ones, so you need to support their experiments and cheer when they need it. If someone's new endeavor is taking up their free time, so be it. You can't expect them to keep their life exactly the way you'd like it to be, can you? Give them freedom and they'll give it back.
