I have a wonderful son...well, wonderful most of the time. We have a good, strong relationship and speak often. He is married to a truly lovely and loving woman with whom we all have a good relationship. What concerns me is the way he so often speaks to her in front of us: he belittles her because she hasn't done something the way HE thinks it should be done. I know she can be somewhat ditsy, and her lack of organisation would probably drive me mad if I lived with her, but it actually hurts me when he speaks so disrespectfully to her (he didn't get this from us), especially in front of us (not that he should be disrespecting her at any time).
I have tried never to interfere in my children's marriages, but after seeing this behaviour on many occasions, I really feel I need to make him aware of something he may not realise. Should I keep my mouth shut - or try to say something (probably by email?) and what should I say?
