Why does he do this to me????

So the other night I showed my husband that I was ovulating and was almost identical. And he throw a fit and asked why I keep testing for. He crushed my heart saying that. Know I want my rainbow baby. He made me cry so bad that I wanted to back my things and leave. This isnt the first time hes done this. I feel like him and I are never going to have kids. And he tells me why he doesn't want sex from me. I'm struggling to my composure of everything that I'm so lost on what to do
