When we filed taxes, we filed jointly the first year and after that separately, even though we were still married for two more years until the divorce was final. But, in my case, I was making the mortgage payment even though the house was in both names.
I would see which way is better for you and go from there. Sometimes it's worth the extra time to see if it's better to file jointing or separately.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
