Nobody Gets me like you.
What does "Get" mean in here? understand or another ?
And how can i tell this I understand you=I get you or I get it to you?
"Nobody gets me like you".

"gets" most probably means "understands". It could also conceivably mean something like "captivates".

"I understand you" = "I get you".

"I get it to you" is not correct.
Yes, understand.

I get you.
