My girlfriend works many long hours and has many other friends that monopolize her time, which leaves us with maybe 2-6 hours on a weekend to be with each other.

In the first month or two of our relationship we would go and do stuff on the weekends with each other, but now the only times we have time is whenever I go and visit her during lunch or during church. My girlfriend doesn't even call me on the phone anymore, and this is making me sad.

One plus zero equals, one. What's left of this relationship (if anything) will not work if she isn't willing to work on it with you. What you and she had was good, but something happened. For some reason, she isn't interested in you anymore.

Of course you're sad. You're being rejected, who wouldn't be sad? Snap out of it! Make a final effort to discuss the relationship with your girlfriend. If there is absolutely nothing there, you don't need to be there either --- move
