My brothers girlfriend (of about 1 year) split up with him 2 months ago. He's 17. It's his first relationship. Since then he's not eaten properly, he won't sleep in his bed (he's downstairs in the living room every night) and he spends all of his day miserable and moping. I know it's not healthy for him and I'm losing my patience with him, I can't pander to him anymore. What do I do?!
