We have only been married 3 years. What am I entitled to?

Your marriage is what is considered a "short term marriage". Most judges in short term marriage cases attempt to place the parties in the same position they were in before they were married. There may be some modifications as a result of specific instances where there has been a substantial increase in the value of an asset because of the efforts of one of the parties; but the general rule is to return the parties to their pre-marriage status.
