My boyfriend ignores me..

I dont understand. It takes my bf hours to text me back and itll say he's active on Instagram. I know that's not always right but I know he isnt busy at night when he gets off work. He never returns or answers my calls.

In person. He treats me like an actual princess. He's all about me and gives me an overload of attention. But when I dont see him for a while (we are long distance) I start getting depressed and insecure and I feel like he doesnt actually care for me or he would text me back and keep conversation...😔
