Should I avoid my whole life?

Heah you said it yourself " I really do want to have and eventually have kids,...........". Thats why God made only for marriage to produce Children out of marriage and not wedlock. Heah it's better God way but like you said it "..... have kids", married is the Best because God made it for that purpose, so continue to wait. In the meanwhile focus on your school work inorder to attain that dream career of yours.
