There's nothing wrong with you.

And also, you are allowed to go with an open-ended ticket. This is something you want to do (and why should other people's insecurities or issues prevent you from doing what *you* want) and frankly, this is no one else's business. I would suggest *not* staying at their place. Find your own accommodation and do as you please.

As for things going sour, you cannot control other people's reactions. Go with your desire for peace and closeness. IF others react or start drama, you do not have to play that game. Retreat and do your thing.
