Finally said I'm done

Tonight was my last straw with my bf of 5 years, he is a drug addict I've tried everything I can to help him but I just can't do it anymore everyone he leaves our house he doesn't come back home until 3 am and I'm fed up I've said plenty times I'm done but this time I mean it he goes to work at 5am so I will be sleeping in my car until he leaves for work I'm packing my stuff and I'm out!!!
