Do I have chance to marry my love? I m born on 21 March 1997 and he is born 6 October 1995 .

Yes, you still have chances to marry him. You love each other so much. But you still need to have longer time to know well and get along with him. Maybe two of you have large differences about the growth experiences. This may lead to several divergences in daily life. Thus both of you are suggested to show more patience and understanding. More communitcations is also important.
