Best friend didn’t come to shower...

I want opinions on if I’m overreacting. So yesterday was my baby shower (my first child) and I noticed about any hour into it, my best friend since we were kids, texts me and asks me when my shower is over.. I say “idk when everyone leaves..” super confused. She never ended up coming, then text me 4 hours later and asked if she could take me out to dinner this week to give me my gift since she missed it.. she said she was looking at apartments all day because their house sold and they’re looking for somewhere else to live. I didn’t reply because I don’t know what to say.

She knew about my shower a month in advanced, and it was only about a 2 hour party, which I feel would have been doable to do both things if need be. I had people that couldn’t make it who either called or stopped by for a quick second just to say congrats, but she didn’t. It’s not about the gift to me, it was having people I loved support me and celebrate with me.. maybe it’s not a big deal though???

EDIT: their house has been for sale for 6 months, so they’ve known they’ve had to move for a while. And when I say “they” I mean her and her mom, she’s 26 and lives with her mom who recently got a divorce, therefore the reason for the move. Thank you for the replies! I’m trying to see it both ways but it’s hard.
