WIBTA if I stopped trying to "keep the family close" when my siblings aren't trying at all?

We’re all adults now, scattered in different cities and trying to make ends meet. I’m the one who keeps checking in, planning group calls, remembering birthdays, trying to keep us close, even when things get busy. But lately, it feels like I’m the only one making the effort. They barely respond, flake on plans, or say they’re “just too tired.”

I get it, life is hard and expensive. But I’m tired too. WIBTA if I stopped trying so hard and let everyone do their own thing, even if it means drifting apart (I think and I fear)?
