Girls, What does eh mean?

I think me and my girlfriend are in a great place in our relationship. We’ve been together for a year and 2 months. We went on our first trip together then shorty afterwards she went on a two week vacation. A few days into her vacation she was her usual self now she’s acting weird I think she doesn’t use name like babe or boo today and she said she’d like to take about us when she gets back but that it’s not a good or bad talk it’s an eh talk. Should I worry?
