Stressful wife 🙄

I love my husband with all my heart. We have had our bad times as well as our good times. But here lately I feel sexually invisible. I have a very high sex drive ( I'm a red head scorpio, a freak in the sheets lol) but my husband is very content. Three times a month is fine with him along with a few BJs. He has now gotten a promotion which is added more stress on top of us trying to have a baby. I try to do as much as I can around the house so he has less to worry about (like making his lunch, laying out his work clothes occasionally) but it's not enough. I have bought new lingerie, try to turn him on many ways, do small things. But nothing seems to help. He says he is too tired. He says I add more stress on him when I try to have sex. Idk what to do. I cry at night because all I want is to feel wanted. He feels bad but he brushes me off, making me feel like it's me. I don't want more pressure or stress added to him. Any suggestions?! No he isn't cheating (trust me I know).
