Do I keep trying or let it go?

25F, I have a good gaggle of people around me and I am very thankful for that. I've had three friends that I am/was super close to move away from where we grew up while I stayed because of my family. We've all kept in touch pretty well over the years, I usually get to see each of them once over the holidays and maybe another time over the summer.

This year, since the literal new years eve and day I spent with them has felt off. These are folks I talk to everyday usually and it's just not there. One of them, Y, has said that me missing her makes her feel guilty; another, W, talks to a friend I introduced her within the past three months more than she ever has to me. My last friend of this little group that's close by just came back from visiting W and S and is now saying he might move to be by them.

Logically, I know it's egocentric of me to feel hurt by this and that if I love my friends I should support them in what makes them happy. Illogically, it feels like I'm being left behind and forgotten consistently. So the ask is as follows: All of us still chat/it is expected of me to chat back, do I ease off investing time into these long-distance friendships or do I keep going as I have?
