I cheated to get pregnant

Before we got together I had always told my now husband that I wanted children. He was always happy with this but wanted to wait until we had the knee for it which was fine. But he kept putting it off and even when I tarted working and saving he still said not yet. I got to 38 before he finally said ok only to find out that he is infertile. We probably should have checked to find out before hand but I wa so desperate and in such a bad bay with baby fever and wanting to be a mother that I cheated with a coworker. The coworker knew that it wasn’t a fling but an attempt to get pregnant. My husband had been told by the doctor that he will absolutely not be able to impregnate a woman and now that I am pregnant he isn’t stupid and obviously knows. We have never mentioned it however and I think he has just accepted that I finally have what I want.
