<human>: I felt becoming more and more worn out since last winter, but I've come to a point where I'm seriously doubting whether I want to continue my relationship or not.  The biggest problem is that she's an extrovert that NEEDS talking.  For her it's natural to be messaging 24/7, and always needs me to be talking to her.  I'm an introvert, and although I don't necessarily dislike talking, I really like my alone time a lot.  I've talked to her about my needs many times, and she is well aware of them.  However, I also know I should respect her needs by at least replying.  When I was first really strongly in love with her, I was willing to take every bit of my time to talk to her and make conversations, but now everytime she messages me about anything I just get really irritated.

Some facts:
It's the first serious relationship for both of us
Been together since last summer.
She's had a crush on me since sophomore year.
She loves me in a very deep and serious way, and often talks about considering future with me.
Although my primary reason for loving her was that she loved me, I genuinely loved her.
I still love her, but it's not the passionate Illgiveupeverythinginmylifetobewithyou kind of love.
I'll be leaving for university in 2 months.  She is expecting us to do long distance.

I just dont know anymore.  I do love her but every time I see her (not too often) I'm not excited, demotivated even, to be with her.  It's kind of like "I have to look happy or she'll suspect something but I can't".  Since she's so sensitive about our relationship I can't even begin to consider dumping her.  She's realizing that I'm not acting the same around her and seems to not even happy to see her, and she's very sad about it.  What am I supposed to do...?

Give me the gist of the text in a nutshell
<bot>: I don't enjoy my relationship with my girlfriend because our personalities are so different but too scared to hurt her because she's so into the relationship.
