is it best i leave him?

my husband said to me that hes depressed and he hates life. i ask him why and he said its because of me. he said i make him hate life and depressed. hes not happy w me, w our lil fam. he said he wish someday he can just be at peace by himself in an island or at mars. i ask him what i do to make him feel this way, and he said i lack too much knowledge and he said he feels like im his kid because he has to babysit me. he said im very boring. he told me he always think about cheating on me cause he cant ever leave me. and im not the kind of woman he wants. it was a mistake for him to marry me. im a sahm and we have 2 under 2. he doesnt even have to do anything but provide for us and drive us around. also, hes abusive in many ways, just not sexually.
