I found this sentence in Cambridge dictionary - I never get to see her now that she works somewhere else Does "that" mean "since" here ? I checked a few learner's dictionaries but could not find its meaning in this context.
"now that" is a unit. According to the Cambridge Dictionary, it is a conjunction. It combines time and reason. The sentence:
I never get to see her now that she works somewhere else.
could be broken down as follows:
Now she works somewhere else and as a result I never get to see her.
