My condolences to you and your family. Losing a loved one in hard man so please take care of yourself. Try to get some sleep and eat right.
As for your W try not to consider everything she says as false or an act. You guys are married and have shared good times together (regardless of what she or YOU think). If you keep looking at your W in a negative light you are only going to begin to harbor some serious resentment towards here, which will not benefit you or her.
God Bless, Eric
