Why can't I say this?
Why can't I say this? He has not got married for two years.
But why is the sentence correct?
He has not seen her for two years.
"get marred" and "see" are all verbs that cannot be continued. Thanks

Answer

The first sentence is not wrong exactly but would sound better with contractions:  Also, the way this sentence is constructed between British English and American English looks a little bit different. This is maybe why you think it is wrong:

He hasn't  got married  for the last two years would be perfectly fine in British English. Some people prefer to say "in" the last two years.

Answer

Who says you can't say the first one? 
It's a little awkward, but not obviously wrong.
