<human>: My girlfriend and I have been dating since high school- for over 5 years now. She's awesome, and most importantly, she's crazy about me. She'll do anything for me and never ask why. She'd spend every free minute she has with me if she could and she often tries.

She's one of the most genuine and caring people I know- what you see is what you get, never any bull**** or smoke and mirrors. My whole family adores her and she adores them. She's awesome with kids, and I know she will be an awesome mom someday. And I really look forward to starting a family with her.

Another plus- she's super attracted to me and is always interested in "making love" so to speak, and is very open to trying new things and doing whatever she can to please me. 

But heres the problem- I've completely lost interest in her. She's beautiful, but i'm no longer physically attracted to her. She's funny, but anymore I've just been getting annoyed with her. She's so honest and loyal and committed to our relationship, but lately I've been feeling very distant.

It's gotten to the point where I feel guilty and I feel badly about myself because I know she deserves someone who would give her all the attention and love she needs, but I cant imagine living without her. She has become my best friend, and such a huge part of my life, but I feel unfulfilled and unsatisfied. 

She knows I feel this way and it hurts her very much. She tries so hard to give me space when I need it and do whatever she can to make me happy, but lately its not enough.

I cant imagine living without her, or having kids with anyone else, or seeing her years from now with her own family... It's heartbreaking for me to think of but I am just unhappy and I don't know how to fix this problem. She is the girl of my dreams and she is crazy about me, but I don't know if I love her anymore. Any advice is greatly appreciated.

<bot>: I have the world's best girlfriend but I am growing apart from her and don't know how to save our relationship. She is crazy about me and perfect for me, but I have been slowly losing interest in her.
