<human>: Can you give me the gist of the text in a nutshell?

So, I have been together with her for just over a year now. The first few months of our relationship was great and I was happy, but now I feel like she just doesn't care anymore.

Over the past few months she has slowly wanting to spend less and less time with me. At first I just dealt with it by keeping occupied with other things, but now its gotten to the point where I am up late at night (I'm currently posting this at 4am) and can't sleep because it bothers me so much. 

In the past couples weeks, we would only spend one day a week together, only for a couple hours. This week we spent only a couple hours together and uses the excuse that it's because of her full time student schedule and that she has a lot of homework. But, I talk to her online, and often she'll be busy with playing videogames. It really hurts because she always says shes busy, but ends up spending her free time with games and just ignores me. When we actually do talk online, She seems un-phased by the little time we spend together and acts like nothing is wrong. It kills me that she can't take even an hour in the middle of the week to spend time with me. 

I've tried talking to her, but she just keep uses the excuse that she doesn't have time because of her school and homework. Am I being too clingy? Am I being too sensitive? I know you need your own space in a relationship, but it's gotten to the point where we barely see each other.
<bot>: Girlfriend of 1 year doesn't want to spend that much time with me, blames it on full time student schedule and homework, yet she continues to play games for hours a day in her free time.
