Partner sleeping all the time

Please try and speak to him about changing his diet and getting some bloods done, my partner was like this but he works nights so has to sleep in the day which messes up his sleep for when he's off for 4 days, but when he does get out of bed around 12pm he lounges on the sofa the rest day, I'd had enough like I get your tired etc but this ain't fair, but he was living off coca cola and quick bites to eat so would be a pack of crisps or chocolate bar or pot noodles whilst he's at work as it's quick and easy, he's allowed me to start making him lunch and start drinking more water and he's feeling much better eating proper food and cutting down on the cola, but he did have bloods done which showed he was slightly anaemic which massively effects energy

I've tried talking to him and saying he needs to go to the doctors, it's been on going now for a while I'm just at the stage I'm done with it all it's making me really down I don't have a life this is not what I want for myself I like going out and enjoying myself if I confront him he calls me controlling. This is just a small problem out of many others I'm going through with him

Then you need to do what's best for you. Tell him the things that need to change and if nothing happens then you just crack on with your life, you only get one and no one knows how short it will be so live it the best you can and that involves you being happy

My fiancé does this but is an overnight nurse in Torrance so he’s working 12 hr shifts most nights and it was a little frustrating but I brought it up to him and now he makes more of his days off with us as a family and gives me time by myself so I just needed to address it with him for us to work as a team and I let him sleep because he works such long hours and is the breadwinner rn but he also makes more of an effort I know it’s hard working on a schedule for what his day offs being helps I spoke with a marriage therapist here and she recommended it!
