Why does my wife always want to travel with everyone else besides me?

My question being the title, why does she even though her main goal is to travel with me and if she doesn’t travel then she gets depressed and down? What am I supposed todo in this situation.

Ok so she asked if I can come with her to Mexico I can’t because I don’t have a passport and that’s about 800$ the last time I looked, and she asked me 3 weeks in advance but really it was 2 weeks and I said no because I don’t have my passport so then she says I’ll just go with my mom which point to the question above, she also traveled to las vagas to help her aunts but really there was another older guy there and she didn’t really respond to my messages at all being there the 5 days. I’m the type that the small things matter most to me but with her it’s the big things that matter most and I’m sick of it at this point like I literally can’t take no more and I’ve told her this time and time again and it’s making me just want to leave her because I tell her all the things that bug me but she does nothing to fix any of the problems she does them more and more
