Right well if you have no kids. Id be brutally honest. Get out now.
My gf has stuck by me. But i want to quit. And i go a month with out and we are a happy family. And we both work very hard. And do not struggle.
Its your life but this is my opinion. Get rid. Tell him come back when he sorts himself. I know its hard losing anyone you love. But hes dragging you down. And hes useing you. It will be hard at 1st. But after you will feel fresh and a new lease of life. Trust me.
Or you can stay with him and give him one last chance. But as you have no kids. He doesnt work. I know what id do. Good luck and ask me out
