Life is a personal journey. Only (you) can hold yourself back.
Each us of makes choices by the minute as to what we want to do next. When I hear the words "current partner" I think of that as meaning "temporary". If I'm just dating someone at the moment with no plans of getting married then I would continue down my career path.
On the other hand if I am married, own a home. have children settled in school...etc I would take into account what is best for my family today and in the future. There would be a lot of factors to consider.
