My Gf is asking for a key to my flat for emergencies. I trust her with my life but I’m scared my key might get in the wrong hands and I get burgled or something. I’ve given it a lot of thought but I’m not sure how to reply without offending her. I know she will try and ask me why and try convince why she thinks it’s a good idea she has a key. She will most likely give me a scenario but it’s more difficult when really I’m thinking well I don’t trust your family and I’m aware some are on drugs and have money problems. What do I do?
