Question about re-entry

Hello,

I have a question which I am hoping someone can help me with. I am married to an American and have the 10-year greencard. Unfortunately, we had to move back to Germany 3 years ago and have been living here since but we do want to move back to the United States. My greencard was issued about 3 years ago so technically it's still valid but officially it's not valid since I've been living out of the country for those 3 years.
So my question is, can I still enter the country?

Thanks in advance for any answers.

Legally, you cannot use your green card if you were out of USA for more then 1 year - after 1 year out you legally lose green card status. They might let you in at the boarder, but might send you away. If you do not have to move to USA urgently, better apply for green card again via consulate (since you were married for more then 2 years, it should be not very difficult)
