"in a corner silently looking bothered through her body language but refused to talk about it (this is how she has always dealt with negative emotions that I can remember)"
She probably felt like she didn't have a voice (in her mind) and that her opinion doesn't matter. All stemming from fear. In the future when that happens, maybe try saying something like "Hey I noticed that you are bothered about something and it's okay if you don't want to talk about it. I just want you to know that I am here if you do." Then give her a hug and walk away. It does wonders.
Forget about her affect on her family, your family, etc. Keep the focus on you and her. You are her H so she's ultimately your responsibility. If you see her family ganging up in disapproval of her, see what you can do to be on her side. Not saying that you agree with what she does, but show that you understand that she has an opinion and that it is just as valid as everyone else's. Women often don't want a solution or being told what they're doing is wrong. Sometimes they just need to be listened to.
How about this...rather than spending the posts writing about all the negative stuff your W is doing, how about writing something positive each time. It could even be about small stuff like ... she smiled when I held the door for her. Stuff like that. It helps to get the negativity out.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
