So some friends that I met a couple years ago invited me to go on vacation with them I immediately said yes because when we hung out we had so much fun. Now I'm not so sure because we try to keep in touch but it just seems like they don't want to talk to me. I text them to talk about the trip and all they respond with is "yup" "I know" etc. not wanting to continue the conversation. Do you guys think that maybe they are just bad at communicating online or that they don't want to go on the trip with me anymore?
