<human>: Can you give me a shortened version of the text?

Hello all,

I heard the talk thousands of times: *high school love never lasts*. While I did believe it, I still decided that it was okay to tell her that I wanted to get married and have kids and grow old etc. We started up a long distance relationship about a year ago when she moved overseas for college and there has been a lot of tension since, including fighting, hurtful words and jealousy.

Recently we argued again, and even though I have recently asked her to stop yelling at me she started yelling again. I live in Country-X and I go to a high school here where everyone goes clubbing on the weekends. The age limits aren't enforced and most kids have cash to throw around so it's the thing to do. She also went to this school and knows that it's the thing to do. We fought about me wanting to go clubbing and she argued that I shouldn't go. I said that if she wanted me to stop I would but it wouldn't change the fact that I wanted to go. She was "defeated" because she thought that because of how committed we were I shouldn't need anyone but her. We then argued over 3 days ending with me not going clubbing anymore and her saying that she will need time to stop the hurt she feels because I want to go clubbing. 

After this talk the thought that me and her were not compatible came back into my mind. It's been festering for weeks. I feel that I need to end this relationship. I'm here to ask for some help on how to do this. These are some reasons shit can hit the fan:

* She is diagnosed depressed and I'm worried she will harm herself.
* We have been planning a 3 month, international holiday to go on soon.
* I have promised her my life already
* We live so far away from each other.
* She feels like she doesn't have any friends where she is.
* She says that I am her "everything"
<bot>: I don't want to kill my depressed long distance high school sweetheart, I want to let her down easily and let her know that it's really just that we weren't meant for one another.
