Despite my objections, my doctors were 100 percent certain unless I stayed on the protocol they designed to eliminate Rhabdomyosarcoma from my body AND prevent it from returning, I had to complete every scheduled radiation treatment.
When I got married, my wife wanted kids. Even though I held onto the hope that I could have children before and during treatment, my attitude always was that if God wanted us to have kids, it would naturally happen.
The final result wound up devastating her and is something that I handled very poorly. As my life went on, I didn't want to be a dad because of the number of health issues I dealt with daily. I was selfish and deceitful in so many areas, and that is a hard thing to live with some days.
Despite never asking for the permanent issues I suffered from, you must communicate your thoughts. Don't allow any possibility for misunderstandings. Even though my attitude toward parenthood changed, I only thought of myself as I experienced the side effects of Crohn's disease and Lymphedema.
In many ways, I am oversimplifying a very complex issue, but the details are way too involved. The bottom line is I allowed my side effects to avoid significant problems that needed attention. It's not easy to live with regrets, so I offer my experience to others as an example. Don't allow your pain to affect someone else's dream. You can't give someone back years of their life.
For the others that are married and one of you can't have kids, that is hard to deal with. Resentment, anger, betrayal, are all feelings that the other feel when they are denied a child due to their partners’ shortcomings. While that might seem harsh to put on someone, they are still are allowed to express feelings of pain and mourning. In most cases, the couple grows closer, but only if both are serving each other in love.
