Hmm, let me take a shot at this. I've been around the block a few times LOL.

First of all, I agree with other posters that if she is only watching what she wants and not doing things with you or even watching TV shows that you like, then she is being too controlling. However, the main thing that concerns me is that you say that she has been unhappy lately. She needs to realize that NOBODY - not you, not another guy, not her mother, not her favorite teacher in school - NOBODY can make her happy but herself. If I didn't learn anything else from a 19 year marriage, I learned that. Way too many people look to other things and other people to make them happy - they look to sex, drugs, church, TV, sports, money, boyfriends, WHATEVER - but none of that can ever make them happy until they find their own happiness.

I was involved in a long relationship where the woman was the most unhappy person imaginable. I beat the hell out of myself every day wondering what I was doing wrong and what I could do to make her happy - and the answer was NOTHING. I could have cooked romantic dinners, I could have given her constant oral sex, I could have have bought her a Lexus - it wouldn't have mattered - until she was able to find her own happiness it wouldn't have happened (and, sadly, she never did). I hate to say it, because I know it is very cynical, but there a lot of people in the world who are NEVER going to be happy no matter what - even if they have someone, like you, who loves them with all of their heart.

Take it from someone who always has tried to be a "fixer" - you can't fix some people. Trust me, I know how it is to love someone who isn't happy - but can you be satisfied with such a one-sided relationship? An old cliche states that you can never love someone else until you love yoursel, and while I hate cliches, I have found that to be very true from my experience.
