resenting husband

Any body just can't stand their husband after giving birth? I've been feeling like that right after I gave birth to our son. Everything he does irritates me. I know I love but I just can't stand him. He gets on my nerves so much . He found me crying the other night in bed. He ask me what's wrong but I just wouldn't share with him cause I know he wouldn't understand. I don't even understand why I feel that way myself
