If you're going to say Gynecomastia, you have to give a reason why you have gynecmoastia as well. Probably easier to just tell the wife you want to grow boobs?

 "I will not support you in it, and if you push it or persist in it, it will be the death of our marriage."  And in another conversation, she said she did not want an effeminate husband, much less one that was growing more so right before her eyes.

I would say that you have your answer. I have read and followed a lot of folks breast growing journeys across several forums on the internet and those who have wives that are against the idea at the start of the journey seldom change their mind by the end of the journey and the marriage usually ends in divorce or separation or miserable wives. Very, very, very few come around and say they love their effeminate husband's new boobs, shrunken, impotent genitals and cross dressing.
