I hope you're ok OP. I imagine these responses may be hard to read for you. Unfortunately, they are correct. You shouldn't feel that you have to have sex to please him and if it's a no, you can say that but it is fair for him to be frustrated (though not to take it out on you) with what is effectively a sexless marriage.
You need to talk and come to some middle ground or understanding. If you're that tired then you need to see a doctor because that's an unhealthy amount of tired.
Please talk to him. Good luck.

I agree here that you need to talk about things and not brush his concerns under the carpet with a “get over yourself”. That’s not a healthy way to have a good relationship with him. You’re essentially just housemates right now, with a pretty sexless marriage. I get it-we have all been there before with young DC, but your youngest is now 18 months, so things should be improving.
I find that without sex, I start feeling a bit shit about myself and really unattractive and unloved. So I suspect your DH most probably feels the same but doesn’t feel able for whatever reason to communicate that with you. Intimacy is the basis of a healthy relationship and whilst it can go up and down over years (ours has, with babies, his depression, work load; now for us it’s teenagers and perimenapause) your post that “it’s been like this for years” is telling. Sometimes, I do think “oh fuck it, let’s have a go then”-but I always enjoy it once we start, so I can say that there can be a “fake it till you make it” moment at times. It doesn’t have to last ages (sweet Jesus I couldn’t do 90mins, I’d be sore and have raging cystitis!) but I always find that the more we have the more I actually want. A quickie can be just as good.
You do need to talk this out properly so that you can find middle ground-but if you’re not prepared talk to him and consider the possibility of making changes then let him go so that he can find a more fulfilling relationship.
