I don't know what to say, but right now I think my marriage is on the verge of failing. I don't know if it is better to stay or go for me.

I can say that I don't think any relationship will make you happy. That is something you have to find on your own. If your expectation is for someone to come into your life and make you feel on top of the world then I think that is a little unreasonable and will only led to disappointment. Maybe try working on the issues that led to your divorce and finding a way to find fulfillment and meaning. Maybe after that, you can find someone to spend your days with that you enjoy to spend time with.
