Should I get married now, especially since I am a university student and well-off? And do the hadiths "O company of youth, whoever among you can afford it, let him get married" and "Three are حق (deserved) Allah's help... and the one who marries seeking chastity" apply to me?

If you fear falling into the forbidden (haram), then it is obligatory for you to marry whenever you are capable. However, if you do not fear falling into the forbidden, then marriage is not obligatory for you; rather, it is recommended.

University studies are not an impediment to marriage; rather, marriage might even be a support for them.
