How should I tell my parents that he is the one I wish to share my life with?
You have rightly said that there is a lot of time before you can decide on settling down and spending a lifetime with this young man. There is no urgency now to broach this subject. Two years is a sufficient time.
Use that time constructively. Concentrate on your work and job and at the end of two years, think the matter over and come to a decision. Right now there is nothing much to do except concentrate on your studies and get a good job and become independent.
