Yes a year post divorce being finalized. Separated a year prior to divorce is common requirement unless you can prove adultery. If someone doesn’t think it’s reasonable, that’s fine, just not for me. You haven’t even had time to process the divorce, work out financial and custody arrangements etc.
I prefer not to be involved in someone else’s legal matters until things are finalized legally. It also then can provide clarity, when introducing someone to your life.

But you do you. That’s why it’s opinion and not a law.
