My boyfriend and I are long distance so we talk on the phone for most days. Almost always when he hangs up he says he needs to do something (or something came up) and will call back. He never does and just texts me later or the next day like nothing happened. This makes me feel like he doesn't actually care about me. I don't want to be on the phone 24/7, if you need to go just go. Why does he constantly say "I'll call you back" if he never does.
