When we first got together we both were going to the gym, I weighed 170 and she weighed like 170 ish both of us in decent shape, since then she has gained 80 pounds… we used to eat healthy eating out every now and then, but now she eats nothing but junk food all day and calls it snacks and when dinner comes around she will eat 5 bites and be done and then 5 minutes later she's eating peanut butter m&Ms and when asked about it she says it's desert…. I tried countless times to address it and honestly it's to the point Everytime she eats junk food I get disgusted, she will literally but a family share bag of m&Ms and kill the whole bag in one sitting eat have a bag of family size Doritos, but when I say something she well you drink monsters they aren't good for you and I reply it's 1 in the morning like a cup of coffee I don't gorg myself all day and skip dinner for more junk food and just turns into an argument. I proposed to her and I just keep pushing wedding of because I'm getting tired of the massive weight gain and the shoveling of junk food into her face… I don't know what to do?
