Guy's Behavior

What does it mean when guys do this?

This guy took me out on a date and he was nice but honestly the date didn’t go well and I thought both sides thought so mutually. There was not much conversation and it was awkward as hell. Whilst he was on the way to picking me up for the date I also realised he is good friends with a guy I was seeing before so that also threw me off the whole idea. Anyway I went with it and I remained polite, thanked him for paying and dropping me home. I said thank you for a good night and told him to get home safe etc and he said “see you soon”. The following day he messaged me saying “hey babe how are you” and again I responded to be polite as I was going to communicate and be honest about how I felt if he mentioned seeing me again but then he literally left me on delivered and never opened my message when I responded to his. What is the explanation to that? Why even message me in the first place? Was he trying to make himself feel better that he got a response and he was the one to ghost me? Or perhaps the other guy mentioned something to him in the meantime (which would be even weirder because I responded in 15 mins) It’s been 4 days and I find the whole thing so strange. I mean he did me a favour as I hate the whole “let’s just be friends” conversation after a bad date but he’s literally 5 years older than me and behaved very bizarrely
