Hello, and welcome to the neighbourhood Fellowship 'round here can be cosy.
He because he feels lots of stress at work, between us, feels tired of putting on a happy face and getting thru the day, lots of pressure (I again offered to leave if that would help--he almost cried at that)
Often when things seem overwhelming, it is useful to break them down into bite sized chunks. What about the stress between you can you own, and therefore reduce so his burden is not too much? I know with NG, my H, when he thinks I am happy with an outcome, he relaxes, When he thinks I am unhappy, he gets would up. So lowering my expectations of simple day to day things helps him feel more at peace.
Looking forward to sharing your journey, it seems to be a very interesting one thus far.
