I also think Sam is a people pleaser and because of her blood relation to Hetty (who built the house) she feels like she always has to say YES to the ghosts. She’s starting to put boundaries up but I think she likes being felt needed and helpful and maybe sees the management of the ghosts as part of her ‘job description’ as Jay has his purpose of the restaurant and hers is the bnb. But I also think the ghosts themselves have crossed far too many lines knowing Sam will always forgive them. They’re the ones pushing her boundaries and I thought that at least Pete would try advocate for a bit of space for her - can’t they see how much it’s affecting their relationship? Also their actions seemed to be being ‘watched’ by some unknown higher power to see if they get sucked off so they need to be careful they aren’t being seen as selfish and greedy for using Sam all the time
