Oh sorry, that's expensive. I hope you can find a color for the toilet to match, or a complimentary color. As to changing the toilet, kids can help doing that too. I changed ours a few years ago and last month I took it up again to replace the ring between the toilet and the pipe. Children cannot handle the heavy lifting part of course, but they can help clean the floor when it's up and they can help loosen and tighten the screws.
Ouch! Don't go saying this to all the women out there who do the repairs, the painting, etc.
I'm sorry you feel that way. Children thrive when they do useful things with adults. It makes them feel valued and competent. But like I said, it does take a lot of love and patience to work with them and you certainly need to be organized.
As to the rest of your post, if your wife wants you to redo your entire home in the hopes this will keep you from crossdressing, I hope that you will learn some boundaries just as you did about going out to support groups. If you both want to improve parts of your house to maintain its value or for resale, or if some things need replacing that's one thing. But just to go ahead for the sake of busy work is quite another. Can your wife help or does she have a full time job.
