Host parents want me to leave

I’ve been here for two months now and everything seemed to be going super well. I just got back from a personal vacation two days ago (I asked for the parents’ permission to go on this vacation when I first arrived months ago and they were very accepting of it). Even the night before I left for this vacation they seemed really happy for me and everything felt completely normal. They knew when I would be returning and I even texted them before my train departed, but the host mom never responded to my text (which is very unlike her).

When I got back to the house the parents did not speak to me and when I tried conversing with them by asking how their weekend went and how they were, they only responded with 1-2 words. The kid seemed really happy to see me and we were talking to each other and spending time together like we usually do. Last night I asked the host mom a question and she responded with “I don’t know, I don’t think we have a connection with you”. This caught me by complete surprise because I had received nothing but positive feedback and before my trip we all genuinely seemed to have good chemistry. I still respected her concern and said if she feels that way then I think it will be best for me to leave because I wouldn’t feel comfortable staying in their home if that’s the case.

She began to bring up the fact that a month ago during a car ride with the family I “barely spoke”. She then said I didn’t text her at all during my vacation. I’m honestly confused why this was the first time I was hearing about something that bothered her last month. I honestly just feel kind of hurt as to why she didn’t say something sooner. She said she will give me time to think about if I want to stay or not. I definitely do not want to but I’m just not sure how to respond or how to not feel awkward/uncomfortable because this happened so abruptly.
