Here’s who it’s not okay to share a bed with:
Anyone who makes you feel like you’re invading their space. Anyone who tells you that they ‘just can’t be alone right now.’ Anyone who doesn’t make you feel like sharing a bed is the coziest and most sensual activity they could possibly be undertaking (unless, of course, it is one of the aforementioned relatives; in that case, they should act lovingly but also reserved/slightly annoyed.
Now, look over at the person beside you. Do they meet these criteria? If not, remove them or remove yourself. You’re better off alone.
