Ok. Gonna be a smart ass here. Are you ready?
With the scripture reading in mind, your mother really doesn't have anything to say about the matter: she should refer everything of substance and importance to the head of the household, your father. And if he is not alive, than that would be the oldest male in the household.
Here's the deal. If this scripture was followed to the letter (and it isn't!), then women would have no right to vote, could be institutionalized against their own wishes, and not be able to own anything- which is pretty much how everything was up until the early 20th century. Why the big change? Women got tired of being oppressed by men and other women who agreed with them.
Your mother doesn't appreciate her own freedom obviously, and in her ignorance is trying to take away yours too. Gee. That's nice.
Ok. Smart- Ass comment over.
These 'arguments' by your mother are a mind-game so that your she can postpone dealing with reality- the reality that you are gay.
Real love doesn't argue. It wraps its arms around everything.
Be the love you seek.
