<human>: Give me the gist of the text in a nutshell

I have been going out with this girl for about 2 months now and I really like her and spending time with her. For the first 1 and a half months things were great we saw each other almost every week and had a great time. Recently, she was writing exams. All of a sudden, she was canceling plans and rejecting my attempts to see her. I know that she is busy with exams but deep down I'm a little worried she wants to stop seeing me but just wont tell me.

This brings me into my next point. She has also become a lot less active when we are texting each other or talking. It always feels like I have to try and keep the conversation going and ask her about her day and how she was doing. Even though I initialed MOST, not all, of the conversations before, now it feels completely one sided. Is this a bad sign? I don't really mind starting conversations, even though I'm not good at it, but I feel like she has no interest in me.

Last thing that is bothering me, am i too needy? I try to see her once a week(she live an hour away but I don't mind the drive) and text or talk to her once a day. Am I expecting too much and needy? 

I know this might seem like I'm overreacting and my best friend, who is friends with the girl, tells me I'm overreacting. I'm just really worried about this because, I really like her and really want to continue to see her. We also have plans for Christmas and I have a nice present picked out.

This is my first relationship and I don't want to mess it up and hurt her in anyway because I really care about her. I'm open to any advice or opinions.
<bot>: This girl I'm seeing is canceling on me a lot and our conversations have been very one sided recently. Has something changed?
