Hello friend, this situation happens to most of the people. Anything that limits your activity will lead to increase in thought process, most of the thoughts might be negative. I will suggest you to get out of the comfort zone as soon as possible, because if it becomes a habit to dislike working outside then will diminish the jewel in you. You need to keep on polishing yourself to shine in life, start will a small work and go on improving and develop new skills, trust me in 5 yrs you will earn more than your wife, and will be more content and happy, because if we sit idle our body tries to destroy itself. Always remember value addition is life. Adding value to everything will add value to yourself.
