Newly adopted adult Coton Only Loves Me - Will this improve?

I adopted an almost three year old male Coton from a breeder. We have had him almost two months. The problem is he only loves me. He puts up with my husband. He just started taking food from his hand a while ago. He barks and growls at my son and girlfriend. He is afraid of most people. a lot of growling.

I have my husband, son, and girlfriend feeding him. When guests come in the house I give them snacks to put on the ground for him. I have been taking him for walks and parks to help get him use to people. I even stand near volley ball games and basketball to get him use to people. He is great with dogs and my cat. We have guests over on a regular basis.

He pretty much just wants me and only goes out to do his business when I am home. He is really great in a lot of ways but I am hoping to get him used to people. I have been doing it slowly. I have seen some progress. Looking for advice. I feel like I will not be able to leave him over night with others. I think it is because he only lived with his sweet breeder and lots of dogs as his pack and never had to deal with visitors on his own.

I will be getting him neutered and signing up for doggie classes hoping it will help. He is so sweet, but only to me. Do you think it will improve in time ??
