One note.
"Marriage", "university" and "career" are a very famous triad:) THE Rails. I don't, know, there must be a book about it: its British edition would be "school, university, career: a person". Its Egyptian edition would be reworked: "school, univerity, marriage". The first person I ever met on Italki, a Russian-French bilingual girl, she had just graduated from school then and wanted to deviate from this path. She became a stewardess and didn't go to unievrsity at all - just in order deviate and try something:)
You derailed at "marriage" station. Well, you aren't a train now, you are a whale or a bird.
"Marriage" is not "your" idea.
It is an idea of your society. And "university" is where you were
told what to do and how to do. Even if you loved that. To continue the same way, in your country the next stage is
"marriage" (a career too). In another country it may be
"career" (and marriage too).
But you can just forget about marriage, don't think about it at all! And try to find what you really want instead. If you know this and this thing is not right here, under your nose ringing your door bell (very often it is, but you don't always notice) - then how to achieve this. May
be it can be applied to career too, if your both choices are not your
true wishes. But the point is: you are not obliged to even think of
marriage. Even negatively.
