Am I getting ghosted?

Hello everyone. I (f/ saggitarius) am seeing another saggitarius. We had a very good energy right from the start and i felt there was a lot of chemistry. He told me from the beginning that hes going to travel for at least 3 months and that hes not looking for anything serious, but also cant hook up with sb he has no emotional connection with. I was okay with that and told him that we can enjoy the remaining time together without planning a future. After 3 dates he postponed the 4th bc he was sick, then texted me 2 times to give me updates on his life and why hes busy. I never double texted or pressured him into something, i know us saggis dont like that. Fast forward last week he texted me that he would like to see me again before he leaves, i replied 1 day later with date suggestions. ever since i havent heard anything from him and im super confused. I know hes not a texter and takes time to reply but idk why he would text me to see me again and then „ghost“ me? He always initiated and texted first but i also showed him very clearly that im interested. I just dk what happened? Maybe some other saggis can help me with this one..? i know his life is super busy bc he literally leaves everything behind and maybe didnt expect to meet someone so compatible like me. Thanks for your help
