Kaylon,

It sounds like your father is very controlling, use to get his own way, and has this undercurrent of anger and judgment.

Good for your boyfriend for not answering your father about his financial situation for it is none of his business.  He was setting good boundaries.

Good that you are in therapy.  Walking away is another way of setting boundaries.  I would recommend you giving clear, direct and honest responses to either parent if they ask why you are not being a “sweet daughter.”

Good recognition that your boyfriend has nothing to do with how your parents behave, it is about them.  It could have been about your dog or job or a friend or the flavor of ice cream that you like.

This is the time in your life to individuate yourself and explore/discover who you are without the tethers of your parents.

Good luck,
Mark
