She does not communicate very well and I got frustrated that she still wasn't happy and wouldn't communicate with me and so I shut down.
Hi Bk
You will see several of us on these boards with this tendency. That's exactly what I did and why I'm here now. You have passive-aggressive behavior and if you don't address it you will have no chance of saving your marriage.
I strongly recommend that you read the book "No More Mr. Nice Guy" immediately.
I also recommend "Hold on to your N.U.T.s"
You have time to read these in your sitch, so take this opportunity as a gift and work on you.
