help..

I've been with my husband for 4 years now. we have 7 month old baby girl. He works very hard every day laying flooring. am I crazy to ask for a little attention? I mean he doesn't hug me, we rarely have sex, barely kiss, hold hands anything. he literally never tells me if I look good. I honestly get nothing out of him. and when I ask, it's I'm tired. he's 22 and I'm 20. i dont feel loved or wanted at all. am i doing something wrong?
