Advice please

So my husband and I have been fighting a lot more after my son was born abt 3+ weeks now. Idk if it's me and the postpartum hormones or what but tonight I had enough! He demands oral sex all the time every night since I'm staying at home with baby most of the time I'm dead exhausted because my son has been having tummy issues and hasn't been sleeping or eating well I've been getting 2-3 hrs of sleep. When not tending to baby I'm either studying, or cleaning the house. We are still "intimate" 2-3 times a week. But he wanted "oral sex" I told him that sometimes I have other priorities, that I can't tend to him all the time on demand. He said he shouldn't even have to mention being intimate that I should want to do it bc I love him. In any other circumstance I agree.ñ sex is a form of pleasure, unity and love. But I'm physically and mentally tired. So he took off his wedding band and told me that when I "knew how to be a wife he will put it back on" it all blew up from there. Idk what else to do. Advice please 😢😢😢
