A (frustrated) Wife's Monologue (part 3)

I'm trying to breathe and stay in control at the moment but all I want to do is scream in frustration and break a lot of dishes (preferably at the hubby's head). After agreeing to have a go at the bedroom, he bails out on me again with another lame excuse (he fell asleep). This is the nth time in 3 1/2 years of marriage. I even had to explain that the ovum only lives 12-24 hours which makes the chances of catching it slim every time he delays. I am so near the breaking point I just want to have that big fight to know what to do next. The last thing I want to have is learned helplessness and that is so against my nature. Where's divine intervention when I need one?
