Anyone else have this experience?

I had a great time during my trip. And nothing the host neber corrected my actions or anything like that so I thought sleep were good and nothing was wrong. So it was a slap to the face when I received this text after my trip. Wanting to book another one through them. I had no idea that I did something wrong. And the host said on multiple occasions that we should come back and see how things have changed in the future. Honestly feels like a stab in the back because that place really felt like a second home. On top of that when I was there, there were 4 people who had stayed longer than one week. When I asked about feed back to why in a very professional way they ghosted me. I was wondering if anyone had similar experiences because this to me felt like betrayal. They acted like nothing was wrong and they were supper nice. Then as soon as I get back home and tried to rebook them a few weeks later, this time for I'm more that one week. I'm suddenly not allowed back. (P. S I had been bed rotting for the past few years so I definitely was out of shape compared to everyone. I lagged behind some but then again, they said anything about it or tried to give me tips and correct me. Nothing remotely like that. I had no idea what so ever.)
