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

So I have been in love with my SO for 5 years. I started dating her 8 months ago. She has been depressed since I met her 8 years ago and it got better and worse at different times. In the past two months, her depression has gotten worse and worse and she was very close to attempting last night. I have talked to her about it and her life is completely stable, and I seem to be the common denominator between normality and depression.

Her happiness has not raised since we have started dating and I just feel like we don't connect and I'm not the right guy for her. I love her and I want her to be happy. She may not be in my life but I want her to have hers. I need to break up with her in the most delicate possible way. That's not entirely possible but I've never broken up with anyone before. Thank you for reading.
