Me and my girlfriend have been together 2 years, we live together, we each pay money into a joint account to cover monthly bills etc. I drive and she doesn't, she says she wants us to pay for everything together, she recently brought a dishwash and now asking me for money the problem is over the 2 years she has only given me bout £100 for petrol, I pay for all services, mots, repairs (theres been alot) and petrol myself, shes always willing to have lifts though. I told her because I pay for the car im not giving her anything for the dishwasher, shes gone off in a mood and called me selfish. Am I right?
