<human>: Hey guys, I really need your help right now.

I have a girlfriend Jacky, of 15 months.  We are both seniors in college, and I am not happy with out relationship.

I have been thinking of breaking up with her for way too long, and I realize it's cruel to wait so long and to live a lie.  She is very very emotional and needy and can't stand more than a half day away from me, and I need my space.

I got a job offer across the country and she has all ready been planning around it to move with me. 

So key notes about why i want to break up:
Shes too needy, I'm too introverted and need my space.
She isn't as active as me or interested in the same things
I am not in love any more
She is extremely anxious all the time and I, being depressive and anxious myself, am really bad at dealing with it and it makes me anxious.

I feel like a complete dickhead.  I have been with her for way longer than I wanted because I was so afraid of hurting her.  She is so fragile and scared of losing me, and I am suffocating in this relationship.  How do I breakup?  

What do I say?  I'm not very emotionally intelligent, and often say the wrong things so I really need your help.
