Confused, am I the problem?

So a guy had taken me for an expensive weekend break. We met whilst I was working overseas and have known each other about a year. He spent around 4000$ and could not do enough for me (this isn’t about money, just was very grateful!) After the trip, he immediately text me to check I made my flight, that he also arranged. We were in pretty much constant contact since, but I am a criminally bad texter. It’s not a reflection of how I am in person. I just don’t really vibe with texts. Anyway, he responded to a message with a tricky reply, that I wasn’t sure how to respond to (maybe slightly closed) I have left him on read and now I’m like argh, am I the problem, and is he seriously interested?
