<human>: Give me a shortened version of the text

I almost didn't write this up here because I'm afraid of getting a bunch of hate about "accept her for who she is" and all. But it's a problem I've been working on solving (with that idea included) for several months now and I don't really now what to do.

my gf and I have been together a little over a year and when we met she was in decent shape, slender, and I loved her body. In the last year, she's put on about 40 lbs and although we are more like good friends now, I barely want to have sex with her. It's not like she's gross or anything, but I'm just "not into it."

I've been trying to look past it for a while. I feel like a shallow asshole, but still the issue remains. I try to get her to work out and change her diet, and I even set the example, but we live separately and she has a kid and a job too, so her time is full and she eats like crap (full of carbs and sugars). 

I'm in decent shape myself, so it's not like I'm the pot calling the kettle black. At this point the thought has occurred to me that I don't want to go on like this. I think it's causing a chasm to grow between us, but I also just don't want to live the rest of my life with someone who I don't find all that attractive. 

Anyone ever have this happen to them? Help!
