HELP!

Hey everyone!! So, it’s no secret that my husband is over weight. He’s always been chunky, but it got worse when he got laid off. He’s now working, but just can’t seem to get rid of the weight. Let me clarify, he’s just flat out not trying. I try really hard to pump him up for exercising, eating right, and all that because I need to watch myself too. I try to make it a couple thing. He recently got blood work done and he has prediabetes and an abnormal liver test. I told him the first thing is to cut back on his drinking and where is he now? Out with freaking friends...I tried talking to him today and he got super snappy when I was just trying to help. I’m trying really hard not to nag, but I guess it sounds like it when the father of my future child is on the road to diabetes. Do y’all have any advice on how I can go about this?
