You are wrong and your ignorance of the matter shows. Before you give someone advice you should check the facts. The age of 23 obligation would depend on what state the divorce occured. No, in my state you are only obigated until 18. I was helping out of the kindness of my heart and the fact that she's my daughter.
You have zero kindness in your heart.
The next time you post a self-indulgent vanity, state the facts up front instead of trolling for answers that you can rant at.
Kindness of your heart?????
Wow, Father of the Year award!
But I'm a sensitive guy. Here's an attorney who undoubtedly feels your pain, and I imagine he'd be quite interested in your teenage daughter's, umm, welfare.
Well then what are you worried about? Cut off the ingrate (both financially and personally) and forget about it. If she's like any normal kid she'll apologize in due time. .....although it could be a long while.
And some folks say irony is dead...
'Goodness of your heart?" Which is more important, the tax deduction or your daughter's life?
With the tact you've shown on this thread I can't imagine why you find yourself alienated from your daughter.
