the only part of this that might concern me a little bit is just how fast he is moving on this major change and whether or not you saw any of this coming. Did he communicate the idea that he might be getting ready to bail on his job that he has been at for so very long.
All i can say is that make sure your feelings are known on what is transpiring... try to find the brake pedal a little bit if you feel it is necessary for you to digest this. You two have to be moving along together as one unit and the "one flesh" tandem with God. I hope he was considerate enough to bring the idea to you and present it to you for your input and your feelings and not just tell you "I will be doing this". If the consideration was in fact given to you ..it seemed you did not mention it or allude to it in what you posted, unless I missed it.
Peace and prayers a plenty for you and your's my dear.
