First question, is this marriage valid?
A: According to the provisions of the Marriage Law on invalid marriage, from the situation you described, your marriage is valid.
The second question is, can you sue him for cheating marriage and let him compensate for the loss of youth?
A: You can get more money, but you are not accusing him of cheating on marriage, nor are you asking him to compensate for the loss of his youth. Instead, he filed a divorce lawsuit with the court and persuaded the judge to realize:
1, you have had problems since you got married (he made him rich and have a good job);
2. Your feelings are not harmonious after marriage (if you get married for a long time and the truth is exposed, he is poor and has no good job, just to get a wife);
The reason for your divorce is that you feel cheated, and now you regret it and want to get out of this humiliating shadow as soon as possible;
4. The current situation of your husband-wife relationship has reached an extremely bad state (which has a negative impact on your work, life and physical and mental health);
There is no possibility of reconciliation (you have made up your mind, you have made up your mind, and you have figured out how to live in the future).
At the same time, he told the judge that he made up that he was rich and had a good job. After being married for a long time, the truth was exposed. He is a poor man. He doesn't have a good job just to marry a daughter-in-law. His cheating is the fault that caused your divorce. He should not divide (or divide less) your property.
In this way, the purpose of divorce and sharing more property can be achieved. If you have little property, you can of course ask the man to give you some compensation through negotiation (you can understand it as the loss of youth). Specific ways and means suggest that you spend money to find a capable lawyer to discuss it in detail.
I hope the above answers are helpful to you.
