I'm too busy for my LDR girlfriend
I am sorry to hear this. Did you tell her that you're busy?
I've told her 1000 times and even if I don't mention it she should still know.
Long distance can be really difficult, but you should try to make time for her if you want to make it work. If you've got time to keep telling her you're busy, you've got time to text her about your day. Let her know how you're doing and pay her some attention when you can.
She's distant and unimportant, so I don't.
If you feel she is not important you should talk to her and end the relationship so she can find someone else.
