Mig, are you talking from a legal or emotional standpoint?
If you have adopted the children you are their legal guardian and responsible for them. Those conditions may be set by a divorce court...but for all practical purposes the adopted children are yours.
Yes, I'm planning on doing the same thing next year. I know that when I adopt them that I will be the person responsible for them until they reach their majority. And I will do it knowing that I take on that responsibility.
