Also, regarding your mother-in-law, that is a typical mother-in-law behavior. I always hear or read stories about how mother-in-laws tend to point the finger at the wife. I know why they might get so protective of their sons. Still, you should encourage your DH to go get spermogram done to see the results. That way, your mother-in-law won’t be pointing the finger at you anymore. I hope that will help you set the record straight once and for all. Also, I hope that your mother-in-law will become supportive. Good luck to you with everything.
