Was my husband really okay with being the sole breadwinner?
Well, if we can manage with that much bread, there is no need to take all the extra pressure along with taking care of the home. My wife is an engineer, and after our marriage, she wanted to do a job, but I convinced her to take care of home, and go for job only if we cannot manage with what I earn. She has been happier since then. That time, there was a little disagreement within her, but now she says, we did the the right thing.
I'm glad that she has been happy and sees it as the right thing, and has no regrets! I think I'll feel the same. Thanks @sanjeevm.
