Most women find me attractive, just not my wife. Am I still the problem/the one who needs to change?

When she gets mad, she gives me silent treatment. I will simply not respond to her. It will go on for days and sometimes a couple of weeks at a time. We will literally not talk for two weeks sometimes because she decided she didn't want to talk to me.

Well this is the red flag in you whole post. I don't consider it that bad of a victim puke, by the way. To start: TRP would say don't cohabitate with a woman (beyond not getting married) because it by default lowers attraction. So backwards as it is, your wife is probably the hardest woman to have attracted to you. You get points because, obviously, she was very attracted to you once (hopefully), but you lose a shit ton of points because you are always there, you're contractually locked into this relationship, she has you... there is no chase, no want, no desire. Beyond this, though, you are definitely fucking up somewhere... the paragraph above makes it obvious.

Now we need more details. What kind of things does she get "mad at?" A few examples would help. Because these examples will show us how you are fucking up. Are you not taking care of your shit as well as you say you are? Are you not being as OI as you say you are? Are you treating her like a wife/woman you want to be with?

In case you don't respond with more examples I'll jump to the next part. The silent treatment. Now, I guess I have probably been in your shoes. I have gotten the silent treatment and my usual move was to freeze it out, silent treatment right back. "Can't show any weakness," I'd say. And it worked alright. Except that now I was going on streaks of not talking for a week every couple months and it made me feel like I wasn't even in a relationship and it built resentment in both parties. I realized I was cutting off my nose to spite my face. Now I make her feel foolish for the silent treatment. I don't do it with harsh words or emotional guilt, I literally make fun of her for it. Someone wants to pout around me and show how unhappy they are like a child? Lol I can't believe I used to take that shit seriously. My level of interest in the pouting depends on how reality based the reason for her being upset is. -Edit: I guess I lied a bit when I said I just make fun of it, I do make fun of the silent treatment part of it (because it really is ridiculous) but... if it seems "serious" I will inquire as to the issue and go from there, this is the part where When I Say No I Feel Guilty comes in.- I could write a whole post on my different responses to "the silent treatment" alone, but basically in my life the silent treatment doesn't last more than 30 seconds because I don't put up with that shit anymore and what I really want you to get out of this is that I don't turn adversarial and throw it right back at her. Eventually you will have trained her to come to you positively when she's upset and you can talk about it like adults. And when I say talk about it, it will probably be her just saying "I'm upset because blah blah blah" and you can kiss her head or give her a hug. You don't have to worry about fixing it, just realize her emotions and comfort her. It's a lot better that having these freeze outs... that is so fucking unhealthy. Please read or reread When I Say No I Feel Guilty so that you can deal with criticism in a less dramatic fashion.

I get that reading TRP can lead you to this mentality and MRP is a bit different on the subject. The answer for your wife if she was a plate? NEXT. But she's not, so your choices are lead her in a positive direction or blow up your marriage and get divorce/child support raped. Every woman you encounter will, most likely, eventually end up acting a LOT like your wife does now, so you may as well fix this one rather than (falsely) think the next one will be better.
