[Arrival] Why doesn't Ian learn the heptapod language as well so he can see his daughter?

We're told the reason Ian eventually leaves Louise is because she gives birth to their daughter despite knowing she is going to die. This is made worse by the fact that while Louise has the ability to go back and "visit" her daughter in a sense, Ian can't as he doesn't seem to know the language in the future. My question is why not? He worked on the language right alongside Louise, and his wife even wrote a book teaching people about the language. Shouldn't he be able to see time non-linearly too and know the truth about Hannah?

It's not just that she learned the language, but that she became so deeply involved in it that it changed the way her brain processed the world around her.

The short story goes into this phenomenon more, setting it up with examples like a culture that doesn't use relative directions (left, right, etc), only absolute (North, South, East, West), and as a result, seem to have an innate awareness of those cardinal directions. But it's not from simply learning the words of the language, but from the way the language requires you to think.
