IMO, he practically asked if he could come home in 3 weeks and you could potentially sabotage that because it is not FAIR
Expectations, or mind reading, or something.
Be careful. This is how the up and down stuff gets started.
All we really know is that he won't have a place to stay in about 3 weeks. Hell, we don't even really know THAT for sure either. It isn't something you need to worry about at the moment anyway.
Stay strong and even keeled. Continue to be kind and respectful but at the same time keep your guard up.
