How should we deal with the problem of marriage?

I want to marry with him so that we can get to know each other better. Sometimes I feel him he will never marry to mine me. How do I to change now?
My good friend had been just got married in the last month, I wished to be her and I envied her. My other good friend is planning to get married in the next month that makes me not content within my heart. The problem of getting married was has been bothering with me for a long time.

Try not to look at getting married as such. "Married" is the result. Try to focus on the process which is the "relationship" and then perhaps one day the result of "marriage" may occur.
