Am I over reacting?? I don’t know what to do but im constantly worried about my husband! he has gained a lot of weight recently ….

he has picked up a few eating and drinking habits that have caused him to gain a lot of weight- I LOVE this man but I hate seeing him treat his body so badly and every time I try to bring it up he brushes it off and tells me he would never say that to me- which he is a very sweet man and probably wouldn’t but This has effected our sex life - not due to looks AT ALL but just no energy and he eats so much he is always too full and bloated to be in the mood even though I beg for him! We haven’t had GOOD sex in over a year it feels like

His lack of motivation to take care of himself worries me about our future together, we are so young (25) and his body can not keep this up long term or he will have a heart attack or something.

My concerns are:

He eats tons of food at once (an entire pizza + beer and snacks all night or a whole stick of butter with a whole box of pasta + tons of cheese ect..)

drinks lots of beer every night and coffee or energy drinks all day long , smokes religiously, and refuse to eat anything that is not meat and carbs (no veggies at all)

He makes me feel like I’m so mean for trying to get him to realize he is starting to be unhealthy but swears because he was an athlete in high school and college that he is fine. And He is fine! but im worries about the future if he keeps this up …

Should I leave him alone or … I don’t know what to do!!! Advice please
