I'm thinking of not letting my girlfriend in my house when she smelled like weed. Do I really need to tell you why?
Oh my, honestly speaking? Has your girlfriend been a problem to you?
I clean up when she comes to my house and I'm tired of this shit.
She should respect your house when she comes over. If she knows you don't like the smell of weed then she shouldn't smoke before getting there.
No. I don't want her in my house. What if my daughter sees her?
Your house is your abode, and if you have rules then everyone is to abide by them even her. You have to put your foot down and make her realize this for sure. Your daughter needs to be protected from this smell and her habit.
