Is the sentence "I didnt get to hear from you for a long time." correct?

It's unusual. You wouldn't use it if you simply hadn't heard from someone for/in a long time. Maybe if you were in prison and they were witholding your mail, you could say that - that is, if the person has tried to contact you, but you couldn't access that communication for some reason.
In what context do you want to use it?

ok! "didn't get to see you" will do.
