Brother in law doesn't like me?

At first he'd raise one eyebrow and look at me in a very judgmental way. I told my husband about it and it stopped. I started trying to be nice making him food. Now he's laughing a lot and very nervously around me. He's pulling his shirt and I'm just confused on what he my be feeling. I obviously want him to like me. I'm more on the shyier side and he seems to be very outgoing with everyone else.
