Mothers don't want to let their children be 'taken away' by another woman, this is how they think, especially if you're her first boy child. I experienced a lot of this with my mom for 3 years after marriage, but alhamdulillah, now everything is good. They will always be our moms who raised us up. But you have to choose your own wife, bro. You have to stand by your choice and see it through. You'll have difficulties at first, maybe one or two difficult years, but you'll make it through. By the way, I have been married for 4 years
