<human>: My wife and I are 32 and 31 respectively, and have been married 6 years, together 10. She's the only girl I've ever been with. 

We've had a rough couple of years, and I found out recently that much of our difficulty stems from her fundamentally changing who she is, in order to be with me. Through the last few years, I've also been changing who I am, in order to 'take care of her' through the tough times. I want to be myself again, and I don't want to be with someone that needs to alter what she wants out of life that much, just to stay with me. 

Along comes another woman, 29, divorced, that seems from my admittedly biased viewpoint to be more compatible with me. She is really strong mentally, easy and fun to be around (I can be myself, and she really likes who I am), and the majority of what she wants out of life matches what I want. 

I have not cheated on my wife with this woman. There is attraction there, but we've agreed to not cross that line. The problem is, this woman is dominating my thoughts, keeping me up at night, and I've realized recently that the thought of not being with her, out of duty to my wife, makes my heart ache.

I don't know what to do. Is any of this remotely normal?

Give me a shortened version of the text
<bot>: Not sure if I still love my wife, Not sure if 'love' I've got for other woman is real.
