You shouldn't need to sacrifice one for the other.
If the love is right then there should be no reason not to pursue the career you have chosen. You cannot live on love alone - the love should enrich and enhance the rest - not replace it
Love may fade/end, so you need to be happy with the career and the environment you are in.
Family and friends shouldn't be abandoned in favour of love. If too many compromises or sacrifices are made then it can hasten the end of the love - becoz of loneliness and frustrations at being away from everything familiar.
Really there is no one solution - every case is different.

Get yourself some cigarettes, a well working lighter, a big bottle of vodka, a jar of pickles and choose career

This also sounds a good solution
