I do not see any problem here unless you have something that you have not mentioned yet in your request. It is possible that it is because of your age. You became uncertain when your family said that it is too early to get married.
However, the girl does not feel that way. Since both of your families have agreed and accepted your love relationship, the time is now suitable for both of you to strengthen this love relationship and prepare well for your marriage.
The girl is a diamond. She proves her love is true and even legitimate and she wants to make it strong by her normal regular behaviours with you and your family. As, I said, if there is something that you have not mentioned, then providing this information helps me see it better.
If there is nothing to add to your request, then everything is well and all that you need is to prove to her that you are honest too. Be creative, mesmerize her by your love, and read more and more to attract her by your knowledge too.
You'll get gifts when you forward, or write. The gifts show you how to use your passion to improve your life, even if you were a student.
Chatora, you wrote your request in one long paragraph and it is full of mistakes. Please, follow the guidelines on the main love consulting page. Thanks.
