I'm considering LandWhaleMaxxing, but I want to know if any guys had experience, with being in a long term relationship with a woman who gets more attractive.

I have a lot of experience with weight loss and I am pretty certain I could get a woman to lose weight easily, the problem is:

I don't know if I would be fixing a woman just for her to leave me for some chad once she becomes attractive. I've heard some stories of guys who've done this and things end tits up
