Friends in some cases, marriage may take place at very early age but later husband takes the responsibility of the girl and educates her. He allows her to make her career and move forward. He guides her and help her. This is common in Bengalis. However, I have seen that such thing is absent in for states people. They think girls are born to serve them. They mostly push their wife back into the kitchen. I have seen my friends crying because of such harsh and cruel mentality of their parents and in-laws.
Its rare that grils get a chance to study after marriage as they get lots of responsibilities after marriage which they would have never thought of. I personally suggest not to think of studying after marriage but should marry after completing education. :)
My best friend, I have told about her many times. She got married when we were studying 5th semester MCA. .....one year before the completion of course. According to her horoscope, she should be married at 23. Otherwise, it may take more years. Such cases also, we can't blame parents.
One girl, she got married and discontinued her PG studies first year itself...so sad :( . How much difficulty she got an admission for a professional course..... It was her parents' decision only
