FYI - I moved back home and into my master bedroom after being separated for several months without my wife's permission - she was furious, angry would be an understatement. When I finally got it through my head that being Mr.Nice Guy wasn't going to get me anywhere with my wife, I had to pull a 180 and stop caring whether or not she thought I was nice - what my wife did to me wasn't nice and she didn't care and me continuing to be nice while she was mean wasn't helping me change anything.
When I stopped being Mr.Nice Guy and started loving & respecting myself, stopped doing things for her and stopped rationalizing her behavior I felt much better about myself.
When you love yourself enough to stop other people from disrespecting you, it's a very attractive quality - it shows strength.
Your response may be that she remodeled the bedroom - my response and yours should be who cares - you can remodel it the way you like it.
Yes this is a bit of a shotgun blast method but the way you are acting now and how she is treating you isn't really proving that your current methods are working.
Never sacrifice your self-esteem, self-respect, self-value and love for yourself. You will teach your kids to do the same because they will see that you stand up for yourself. If your kids grew up and got married and found themselves in the same situation, you would love them enough to tell them to stand up for themselves - time for you to love yourself enough to stand up for yourself.
