I feel he's sabotaging our chances

My husband and I have been TTC for a few years. We found out earlier this year that his sperm count is low and I have a hostile environment. He also does not want to adopt, will not entertain this conversation even.

Since finding out, we've redone our diets as best as we can. We've swopped full sugar drinks for sugar free, and limited this as well. Limited coffee, started drinking more water and green tea and healthier teas. Started eating better. Spending a fortune every month on doctor recommended supplements. I've been exercising more, him not so much but he says he spends a lot of time walking around at work.

I prep his lunch for him and make sure to include good foods and fruits.

I get upset with him because despite the fact that I ask him nicely not to , he still buys junk food for the house and at work. I know they have a super unhealthy meal at least once a week, I can tell by the way it bloats his already pot belly. And I am very weak willed in that regard so that's why I'd rather not have the temptation.

I also get upset with him because every Friday and some Saturdays, he drinks with his colleagues after work. Now most of you will probably say that's not a big deal, but when he's got poor sperm quality it is a big deal. He also still drinks more than couple of energy drinks a week (I drink maybe two I need that boost here and there).

Now today, I find out that they have Coco-Cola pretty much on tap at work and he drinks a glass or two a day. Again, might not seem like a big deal but when your sperm isn't up to scratch, all these things that have been PROVEN to have an adverse effect on male fertility, it is a big deal.

I feel like he's really just sabotaging our chances at having kids. I take five different kinds of supplements a day (Vitamin D, CoEnzyme Q10, Iron (anemic and also read that low iron can negatively affect female fertility), probiotics, collagen, Vitamin C), he takes the same but no iron, plus he takes a stress management supplement per the doctors recommendation, we eat better, I exercise like I'm training for a marathon and it's all sabotaged by unhealthy food practices at his work. 😔

EDIT FOR UPDATES:

When we explained the dietary changes to our doctor he was very happy and said that it definitely should help, especially with him as his lifestyle habits have been proven (via semen analysis') that his count and such improved. He had another analysis done after some of the initial changes, a few months after the diagnosis and there as already an improvement and my husband was really strict with himself easier this year. Now he just doesn't seem to care. He's also the one who initially said he wanted us to have kids too. He brought up that convo and has happily been attending any fertility appointments as necessary.
