This is so sad to read. You've stopped living your life for fear of climate change. It sounds like you're even compromising your marriage!
We won't solve climate change by consuming less. That was a temporary measure. We must replace fossil fuels so we can live more.
What you're doing is equivalent to solving population growth by sleeping more. Population remains the same because you're still alive.
Get involved in substantive change. Work for a green company. Invent something. Write to your representatives. Fly to conferences in support. And for god's sake buy renewable energy so you can turn up the heat and keep the lights on!
You're not helping anyone when you remove yourself from the solution.
