If she wants to marry a doctor what is so bad. The only problem is until he graduates and finishes his residency he is 27 and in debt to the tune of $3-500,000.00 in student loans, unless he has rich parents.
When is she marrying him? Before he graduates she may have to support him. During residency they work him half to death so I doubt he will have time to date. After finishing residency he is 28 going on 30. He will be working multiple jobs in order to pay off his student loans.
Just remember with Obama Care there is a limit to how much a doctor can earn and likewise there is a limit on how much a pharmacy can charge which will effect future earning.
