Getting her to lose the weight?

First time poster. Long time lurker. Been workin on RP for about 1 year and man oh man has it changed my relationship with my wife (and my life in general) and changed the way I view myself and the world. I won’t get into all of that.

Here is something I’m struggling with:

Wife has slowly blown up over the course of our marriage. We are talking going from a healthy 130/140lbs to slightly over 200lbs today. Typical story about how after she had our child she never dropped that weight and has continued to gain weight ever since. In comparison I’ve always been in shape. I picked up weight lifting again a year ago since it’s essential and I’ve fallen in love with it. I lift six days a week, hit all muscle groups twice a week, and every session is 1-2hrs in length. I built a basement gym and I’m obsessed and it’s really become a zen hobby for me at this point. Love growing and see my body building up. Even before weight lifting tho, I’ve always been an active good looking guy. I’m blessed with great genetics from my parents.

Now, I can’t lie and pretend that I didn’t have a covert contract in the back of my mind when I started red pill and weight lifting (im looking the best I’ve looked in 10 years physically). I’ve never confronted my wife overtly about her weight gain. Before red pill I always made passive aggressive comments about “other people’s” weight, certain junk foods that “other people” eat and those types of “maybe she’ll look at herself if I say this” comments.

I’ve backed off on that stuff a lot. I understand the concepts of stay plan same as go plan, trying to kill off resentment and be a positive clear headed captain and I also understand the concept of the 1000 ft tow rope that Rian Stone talks a lot about on his YouTube channel. 1000 ft tow rope is what I've been telling myself when it comes to her weight for the past year

So here I am a year later and my wife’s attitude and actions are way improved. I’ve reclaimed my masculinity at home and at work and I’ve put the captains hat on. All while keeping a light and fun attitude and avoiding going Rambo or getting resentful (actually did have the anger phase the first 3 months or so after learning red pill but did a lot of stfu instead of lashing out to deal with it). My relationship is in a good place with my wife. I never get turned down for sex and I’ve been getting BJs every time we fuck for like six months straight where I didn’t have a BJ for over five years before red pill. She cums during sex now too most the time which she very rarely did when I was blue pilled beta (can thank ‘sex god method’ for a lot of that).

But, she’s still fat and not doing anything about it. My SMV is way over hers and the only thing I can think to do is be overt and tell her “you need to drop this weight”. I would prefer not to just nuke the marriage over the weight thing but it's a huge deal to me as time goes on and nothing changes. The more I lift weights and get hunky and good looking and have changed my attitude towards women the more I recognize I could pull so many hotties if I was a single guy. So why put up with a fat wife? I’m not afraid to loose her if push comes to shove but I do enjoy my wife and our family and friends how things are. So, I could very easily get with younger and hotter women at this point in my life if I did nuke the marriage (I’m 32, good looking, good job, car/house etc) but my biggest sticking point beyond actually liking my wife is keeping the family together for my kid. I haven’t been able to cross that rubicon yet where I’m okay with the kid growing up in a broken home. Maybe I will someday.

I like my wife, we get on great, but how can I get her to drop the extra weight so I can have my pre pregnancy hottie back? Do I just keep telling myself "1000 ft tow rope" or should I be overt and tell her to lose the weight? As as side note, I've noticed that in other areas of improvement being overt/clear with her was effective.
