Is this normal?

My BF and I have been super close for the past year, like peas in a pod close. He is my best friend.

Lately his family has taken it to be very vocal to him that they don't like that, and threatened to send him to his mother. (She had recently moved away, and since he has only a year and a half left, he stayed. ) So we decided it was best not to give them reasons to not like us being together, distance and no hugs or hand holding and such. At school I figured we could still talk and hang out like normal, but for the past week it feels like he has avoided me. He says it because he has classes he needs to focus on and I believe him and try to be supportive, but I can't stop feeling sad. I mean, I use to look for him all the time and now.. I don't expect even a text anymore. Is it wrong for me to cry over this? It's not like he is mean or obviously lying about it, we're just drifting it feels. I don't know what to do, it just hurts and I feel bad because I'm being sad over something like this.

I agreed we should have distance around his family, and his grades come first. I just don't feel like I agreed to be alone.
