Your getting it, bud! If some of this stuff can get through my thick skull, there's hope.
Just a couple of things for you. If you choose to write her a short note, I'd recommend you not use vague words like "perhaps" or "possibly". They send a message in writing that you are not totally owning up.
As it says it the WAW column, thank her for "nagging". She's communicating with you when she does that! If the timing is right, you can make it into something humorous, but let her know you are not brushing it off.
Whether you sell it or keep it, do not, I repeat do not, put this house above your wife...
I know you are a real estate dude, but what does your wife think? What if she said something to you like "I'd rather just rent than have these headaches that comes with owning a house right now". She may not say that, but you NEED TO WANT her input. She knows you are a real estate dude and in her mind that may be why she has given up on discussing it.
I also want to thank you again for your kind post to me. It's amazing how reading other people's situations can reveal things about my own situation. Much of my advice is to the guy in the mirror as much as it is to you. Thanks again.
