No sex

I am married to someone 22 years older then me, sex has been difficult for us because of Ed but i think my husband has just given up on the idea of sex altogether. I have tried and he shows no interest, i came home early today and thought maybe we could do something but no he is outside splitting wood. Yes it has to be done but not right this second. I get dressed up for him i rub him and i get nothing no touching back no touch of any kind. What do i do?
