<human>: My girlfriend of 9 months went to college a week ago. At the start of our relationship I gave up all of my friends and relationships to be with her and this summer we spent every day together. Now that she is at college I don't have anyone to talk to and she only calls me at about 1 AM every day and once in the morning. Every time she has called i have been sad and generally depressed feeling because she has made a whole group of new people that she uses to substitute me (her words) so she doesn't miss me. I on the other hand don't have anyone right now and she has been choosing time with her friends over calling me. The latest example is that she didn't call me at 1:00 because she had to play uno with her friends. Now she says my sadness is making her unhappy and she will break up with me if I dont get over it. I love this girl more than anything but now she says I can only call her once a day till I learn to be happy. Please help me

Give me the gist of the text in a nutshell
