A mother son relationship is similar to a father daughters, but there are differences. I am sure some of you will say that it is true a mother and son have a special relationship and has been stated by psychologists as the Oedipus Complex or something else. I am not sure I agree with Freud on everything he has stated, but it is true that a mother and son share a different kind of bond than a mother and daughter. There are other psychological benefits for a mom and son to have a strong bond, but you can go do a google search on that topic.
In our family it is easy to see. My wife and son have similar personalities, temperaments, ways of handling things, interests, getting drunk the same way when we were in the Bahamas, they are both people persons, and many more. My son will talk to his mom about most things before he will talk to me and that is the way it is.
My son is the baby of the family and I am sure that has something to do with it, but I am sure there is more. With my own mom as an example, I feel like I need to protect her at times from my dad. Do not get me wrong, my dad is not physically abusive, but he can be mentally abusive at times. I do not think I am that way, but with my aggressive personality I could see my son trying to protect his mom from me. I find it easier to talk to my mom than I do my dad. I can disagree with her and I do not feel like her love for me has vanished. He wisdom is amazing. I am sure my son feels all of these things and more.
If a boy has a strong healthy, loving, and respectful relationship with his mom, he is more likely to treat his wife the same way. However, moms cannot always interfere in their sons affairs or they will not grow up.
