So you enjoy porking a 215lb lardass over a nice trim 115lb chick? I have been with both sizes and can tell you that you are only kidding yourself.
The sooner you make her change (or leave) her the sooner you will be happy. If not in 10 years when you are stuck with kids and the only option is divorcing her and paying child support alimony and giving her everything you have worked for while she was downing baconators you will regret not taking my advice.
You are free to do what you want but realize you are only selling yourself short in the long run, the sooner you put a stop to this gluttony the better of you are going to be.
