Should I reach out to her less?

We're two friends in our thirties. She had a baby in the summer and we live about 2000 km apart in Europe, while I'm childfree and single.

From what I've heard, parenting is going well and the kid is a good sleeper. Her love life & social life are doing well and she seems happy.

For the last few years, it's been mostly me to reach out and initiate conversation. I'd ask her how she's doing or shared something funny, and then we'd text for a bit before going on with our daily lives. She's never seemed annoyed by that and when I asked her about how she felt about it, she said she liked it.

But... it's started to bother me to be honest. When we see each other, it's mostly me who travels to see her or initiates the video call. I've probably prioritized her higher than she's prioritized me.

Now that the holidays are here, I've limited texting her, and the phone has been really quiet. She hasn't initiated conversation and I've let it be. Christmas can be busy, but I can't help feeling a bit sad.

Should I go on with the radio silence and see what happens? How have you navigated similar situations?
