Need help wit my girlfriend?

Any long distance relationship is difficult and a lot of work. You guys are both busy with your own lives and it is understandable when it seems as though she isn't as caring as other times. Don't let it get to you unless she outright says she doesn't care. Keep your head up and look forward to the times when you will see each other. Maybe you guys can talk on the phone more than text cuz phone calls are a bit more personal.
