It is unfortunate that your mother does not see the value of the man you have chosen. Parents want what is best for their children. They often have preconceived notions about how that child's life will evolve. What you need is an honest dialogue from your mother. There is something about the man you have chosen that is setting her off. Possibly this is happening because she had an issue at some point in her life that fostered her beliefs about people. You have a master's degree so you technically do not need a man to support you. What is she afraid of? Ask her. Also, ask her if she thinks this man has a significant character flaw that makes him a poor choice. Money doesn't make up for character. As for how you will get past this, you won't, she will. In time she may eventually accept him. It is frustrating, but time is really the only healing force in these situations.
