Thank HN: Five months ago, I was feeling like a loser, now I am opposite
Just a suggestion, but if your relationship with your wife depends on your personal circumstances and mood, then it sounds not very strong. Might be worth taking advantage of this good period to do some relationship strengthening exercises while you can so that when the next downturn happens, you can both understand each other's and your own feelings better. I'm not talking about random activities like going to the beach but finding a good self-help book or therapist and sitting down together working through it regularly. It's easy for problems to grow silently until they're too big to fix. Relationships are far more important than jobs, money or houses.
