It is possible that this is your father's technique of parenting where he motivates you through negative comments. He might have found it effective such as the example of your success in your job and he is now continuing it without realising how negative his approach is. Your father may not able to see the negative effect that it is having on you. You need to speak with him about it. You are grown up and are in a position to make your own decisions, so it is not necessary to consult him for every decision. Also it is important to realise that since you have to live with the decision you make, your own need it is most important. This is true not only for your job but also with your marriage. Discuss the topic with him and don't give into pressure. Try and focus on your own needs and on understanding yourself better. Introspect and if you are still unsure seek counsel from a professional. You may even have a counsellor at your work place whom you may contact.
