AIO if I cut off my friend by ending our snap chat streak

I met this friend 10 years ago we became really close but then I moved states away but she always messaged me and we kept in touch.
Around 150 days ago she started snapping me and I started snapping back to keep in touch I thought it was a beautiful idea since we don’t live near each other and thought that’s how we can keep up with each other but…
I realized that it feels one sided as in yes she always snaps first because she wakes up earlier and my theory is she has other friends she snaps too. Well if she snaps oh I’m not feeling well or oh it’s so and sos birthday and I always follow up and ask more but she doesn’t. For example I said oh my dog is 13 today she just opens it and that’s that. Which I thought okay yea it’s fine it would be wrong to expect her to say something it’s just “my dog” but recently she said “ I am taking my dog to the vet about to spend $$) and I followed up asking if they are okay. Well ironically just two days ago I snap chatted her saying at the vet (with a pic of my dog) … she didn’t respond. So later once I picked him up I snap chatted “he’s still drowsy” and nothing she just opened it… am I over reacting. Honestly, I have no other close friends so I just feel like I am wasting my time worrying about oh I need to remember to snap back when I feel she doesn’t really care even though she is the one that started the snap chat streak.
