You’re such a good son! And I’m sure you’ll make a good husband to. I say go for it! Your mom is giving you the go signal, and you’re doing a good job reassuring her.
But I want to tell you a secret. I have three brothers and one is married. Moms who have sons BIGGEST concern is that you’ll get so caught up with your wife that you’ll forget about Mom and abandon her----or move far far away cause your wife wanted to. So it’s good that you’re reassuring her, but even better would be if you girl could talk to your mom-PRIVATLY. This is what she should say:
“You have done such a great job raising your son, and your son respects and cares about you so much and I will try try my best to the best daughter in law for you, because I know it would make your son very very happy. I just want to reassure you that we plan on staying as close to as possible with you, and I hope you are okay with me marrying you son.”
or something to that extent. Your mom will love her to death then. Either way make sure YOUR GIRL is reassuring your mom, not just you (your mom already knows your the best little boy, who would do anything possible for the mom- she needs reassurance that your girl won’t brainwash you and dump your parents).
