How to handle a person whose pride is too high to reach?

Tweet

Suggestions and opinions are very welcome! My dad's pride is so unreachable to the point where my mother gave up talking to him already. He used to have a job but unfortunately was bankrupt so up until now he doesn't have a job and has no intention of finding one. He has some side jobs like selling coconut wine "Tuba/Bahalina" and rent from our warehouse but that's it.Sure, I'm thankful that he has money to support our family but the job is too stressful. A lot of opportunities were given so that he could work without having to worry about stress but no he doesn't like them because he is too picky. My aunt offer to buy him a car so that he can travel and earn money as a taxi driver but he doesn't want to because it's degrading and tiring ( His sideline job is more tiring, he has to use his car which is hot 'cos the air condition is broken and has to travel for 2 hours just to deliver 10-15 containers that are heavy than he is which in my opinion is more tiring than being a taxi driver. Oh, he earns around P400 for those sideline jobs). Another thing, his brother-in-law offers to give him a job from his hometown and still he refuse because he doesn't like to because he wants to be the boss not working under the boss. He keeps preaching me about never to picky when finding a job and then he starts telling me the jobs I LIKE to work at are degrading(barista or chef as an example). Look whose talking... My sister and I were traumatize as children with all the things he did to use and not even once has he ever apologize with what he has done. He keeps pushing us away, giving rude and sarcastic remarks to us and we didn't even do anything. He looks for ways to provoke so there will be a fight. My mother gave up talking with him 'cos he just throws them out of the window. He thinks he is always right even if he is wrong. When we tried to correct him he gets angry. Do you think he needs counseling?
