Not Saying Too Much These Days

These days my spouse does not have too much to say when we talk.  He still calls to check on us but once he hears everyone is fine or I update him on something regarding one of the girls, the conversation is over.  He would periodically call me during the day to say hi, but he has not done that for a while now.  He works a 24 hour work shift so I will call to check on him if I haven't heard from him just to make sure all is well.  Even when he stops pass the house to visit, he does not visit long.  He may chit chat a little bit but he just seems to keep the conversations brief.  At one time, he would want to talk like what seemed to be forever.  If he stopped pass the house to visit, he would stay and have dinner if I offered.  He took the girls to a carnival on Labor Day. When they were about to leave,  he asked one of them to call me to see if I had cooked dinner and I had.  In the background I heard him say good.  I figured I should make extra because he is coming in to eat dinner.  He dropped the girls off, never got out of his vehicle and declined the dinner offer. I must admit, that I was caught off guard when he said no. Later that evening he did call me to say thank you for the offer but he had stopped and picked up dinner for himself.  I am not afraid to admit that I am a little confused about this new behavior.  Not quite sure what to make of it.  Is he finally accepting the fact that the marriage is over?  Is he seeing someone?  Stop playing the guessing game and just ask him What's Up?  The truth is that the answers to any of these questions does not really matter.  I have to remember that my wifely role has changed, I care about him but he is not one of my priorities any longer.  I have been a wife for many many years so old habits can be hard to break.
