I’m sincerely glad to know her father would hold you to it.

Based on current marriage law there’s definitely a case to be made that it is not true marriage by scriptual standards. A woman should never be able to strip a man of half his material possessions and his children. No matter the reasons. There was never any allowance for a woman to leave a man, only for a man to put away an unfaithful woman. Which is really a means of protecting a woman’s right to providence from the man as long as she remains faithful. It puts her security in her hands based on her behavior. But it does not give her control over his wealth.
