Social situations causing problems

Asalamu Alaikum Warahmatullah,
I like and I love a muslim girl and I have known her for one year now we have been intimate and we both intend to marry each other but shes 24 and I am 22.Im from India I am still studying and there has been some pressure from her parents on her to get married.
Although what her parents want is right according to islamic shariah but the problem is that we both want to marry each other as we have also been intimate. I beg Allah(SWT) to forgive us for such a sin but now we are greatly attached to each other. The social situations here do not allow us to get married before i am not earning and able to support a family. For that she has to wait almost for three years so that I can become something and then try to marry her. On the other hand she says that she can delay for maximum two years due to the pressure building up from her parents which makes the situation very difficult for us. Being 22 years old I still cannot talk to my parents about our marriage. I can only do that after Im done with my studies and then I have a job. She being older than me makes the situation hard for us.

Please tell me in this case what do you suggest? Also having been intimate now is it necessary for both of us to marry each other?
I assume that you can say that we should tell our parents about our intimacy but I don't think we can? Please help and advise me on this matter. Thank you.
