Three friends (a couple, M37 and F23, and one M33) of my (F37) bf (M41) are visiting us over the weekend. I have a big house with a garden on the back. They’re all smokers and keep smoking non stop on the garden; it’s a very small garden though, and they smoke a lot, so much that I can smell cigarettes in my kitchen and living room. I don't like the smell and I'm not joining them, and sometimes I go on long walks my dog or go read in my room because I'm very bothered by the constant smoking and the bad smell. Yesterday evening we went out for drinks, stayed outside and they kept smoking at the table, in front of me, without asking if it was ok. I will also mention that, when we're at home, immediately after breakfast, lunch or dinner they all go out in the garden to smoke and stay there a lot, so I always do the dishes/cleaning by myself. When I talked to my bf I said it’s rude not to ask me (I own the house btw) if I'm ok with them smoking on my face all the time, and that they’re basically excluding me in my own home. He said I'm too sensitive and I'm overreacting. AITA?
