Marriage Vs career

I don't know what I want
I once knew but now I don't
Someone proposed to me and he is really great he is a law student he is smart has a good heart and I care about him but I said no cause I knew very well I wanted my career more
I am still a student and I want to move to New York start my life there and try to be successful
However for some reason idk I have been bumped out
And I am starting to questions everything
I am starting to question what I wanted
Do I want a family and a calm life
Or I want to live in New York
And strive for success
Idk what seems more worth while for you

Keep in mind I can't have both because he can't move with me cause it's too complicated for him or it's either this or that
