We just had our first child in Oct and wife is gaining more weight. I've been going to the gym and getting my muscular body back while encouraging wife to come but she's always saying she's tired. I take care of the baby more than her. She might go one time and then that's it. I've tried being an example, motivating, even begrudging when I see she always is eating popeyes and other fatty stuff. She eats a lot, sits on the couch and watches videos. She never wants to accompany me to the gym even when I take the baby with me as a sign for her. She is getting so fat and I'm no longer attracted to her. She keeps insisting I tell her I love her but I really do not anymore. How can she be so lazy? I'm getting my pre baby body back (really muscular) but she keeps getting fatter and fatter to the point where she hides her body in pics. Wth can I do? I'm on the verge of leaving. Advice please. I've tried everything guys. I'm confused and so overwhelmed at how she can be so lazy and not wanting to take care of herself. She has massive love handles and rolls of guts and it's exasperating.
