Not being able to respond every single day is not "ghosting you".
I do always reply but I sometimes need a day or two because I don't like hastily typing a few words on my phone. There's no need to become unkind just because you haven't recieved a reply the very next day. I'm only human, I do other things in the offline world and I do sometimes need a day for myself, too.
I haven't seen much of the world yet, I've mostly been in Europe but I've visited GB (London), Spain (Barcelona), Greece, Turky, Sweden, Denmark and the Netherlands. And obviously various places in Germany. I can't decide which country I liked the most, I just love seeing new places.
