Uh, I don't understand your question. A man would compete with a woman for all the reasons anyone competes with anyone. Dumb question, as it stands.
OH, why would a father compete with a daughter? That's NOT the same question, is it? Completely DIFFERENT question.
He has a mental health problem, where he can't bear the thought of you doing anything better than he does.
If he's so psycho as to go hungry, let him.
So your REAL question is why your father is verbally and emotionally abusive. Most likely because that's how one or more of his parents treated him.
BTW, are you a woman? Or are you a child? If you're an adult, why not move out, so you never have to deal with him again?
????? Why don't you lock your stuff up, whenever he threatens to get rid of it.
You're not AT ALL asking what you PRETEND to be asking.
You probably need some counseling, as being raised by an abusive parent has taken it's toll. And if you're working, then why not move out?
I'm sorry, but you're very stupid. There's no point in trying to reason with him. There's no point in asking him to do favors for you.
And it's stupid to take any of what he says seriously.
Get OUT, and get therapy.
Edit: BTW, you could have told all of this in MANY fewer words, and without repeating yourself, and going on and on. AND you could have mentioned the most RELEVANT stuff.
Anyway, move out, if you're at least 18. If not, talk to someone who can help you.
Actually, all the kids need to be removed from his jurisdiction, if not him removed from the home.
talk to your school counselor for a start.
