Why are you with him?! You are only enabling him. He doesn't pay for anything (why would he as you have been providing for all his needs the last 10 years), he is negative and you always fight.

Why are you tolerating such behaviour? This doesn't sound like a relationship but someone using another for free rent and food. He doesn't want to live with his mother, so you let him continue to use you?! You are only enabling him. Is that the type of relationship you want?

And sorry but staying in a relationship because one doesn't have a car or mode of transportation is not a good enough excuse. You work and are earning a living - get an Uber, have home delivery, get a bike, ask a friend or relative for a lift. Likewise, get driving lessons from someone else (friend, driving instructor). You don't need that parasite.
