Sex talk & relationship

(If this isn’t allowed here, please just delete it) I want to open my relationship with my husband, not to anything sexual, just emotionally and affectionate wise, he’s never home, i’m stuck at home with our kids 24/7 365 days, and i have no problem being a SHAM, i chose this, but i have no emotional or affectionate from a adult, and i feel so fucking alone, but he refuses, he says the little affection i can get from him, should be enough, and that if i wanna open the relationship then i should divorce him, i dont want to divorce him, i just want emotional and physical affection that isn’t sexual (that’s the only affection i get from my husband) what can i do? what should i do? i’m struggling

I’m 23 and already have a 2 year old , I have been trying for my second now for seven months , I know it can take up to a year but are there any tips or anything to help , starting to feel disappointed seeing the negative tests
