Husband giving me a hard time

I’ve had a little disagreement with my husband Sunday, and I clearly was upset. Since then he just doesn’t bother to be “good” again. We talk normal about day to day stuff but he doesn’t even try to be close to me, he even avoids physical contact all together. Today, he gave me a peck before he left the house but that’s that. I have always been the one to come to him, but this time I’m not. I don’t understand this behavior? It really hurts me
