Dear LIB readers: At what point should one walk away from a childless marriage?

Hello Linda, a question for your readers. At what point should one walk away from a childless marriage? I'm a healthy female who can bear children but married to a man with a very low sperm count. The doctors say our chances of having kids are slim but possible, but I've been waiting for six years and I'm fed up, especially now that I just turned 35.

I love my husband but I want to be a mum so bad. After six years, is it time to walk away?
