<human>: Hey everyone, I have been dating a girl for nearly two years, and  throughout our relationship I have continued to doubt where things were heading.

I want to be clear, she is a very good person, and can undoubtedly make someone very happy, but she and I are very different and it's becoming more apparent every day.  We are both college students, but in recent years I have turned my 'party hat' in for a 'thinkin hat'. However, this is not the case for her; she still likes to party and often gets upset with me for not having enough "fun".  Additionally, she is very competitive, so I often feel the need to hide my academic accomplishments so I don't upset her.

I could go on about other trivial differences, but I think you get the point-  she is a good person, but I don't believe she and I are a great fit. 

With all of this in mind, you may understand why I am considering breaking up with her, but now I have to explain my apprehension: after dating for a while I learned more about her mental state, and I am scared of hurting her. 
I don't think she would respond too tragically or anything, but I do believe she would blame herself, likely for several months.  Though it is cliche, the whole 'I love you but I'm not in-love with you' thing applies and if I could wish her anything in the world, it would be happiness!  But I am ready to break up; I just don't know how to go about it and how to minimize/prevent her from blaming herself.

Can you condense the text into three sentences or less?
<bot>: How would you break up with someone you still care for but has a tendency to blame themselves, and enter prolonged depressive spirals.
