It does not appear to be any foundation for a case of fraud, because you willing gave him the money - however, if he went into your wallet and took the money, you can file criminal theft charges for the $1000. However, it could be a s/he said situation. Witnesses would help you.
I do not see how you were conned - you willingly entered a relationship. Surely, you do not feel that giving money to someone means they will be with you forever or that your money could buy his love.
If you have information that he did not actually lose his job or the $2000, I cannot see how that will make a difference. You willing gave him the money without a contract to repay it. Unfortunately, he lied to you. You did not have to believe him. It is a sad commentary on our society, but we have thieves among us and dishonest people among us.
If you want to use the note on the $1000 he took, then you could try to sue him in small claims court. However, I suggest, a court will see this as "sour grapes" because he is no longer in a relationship with you.
Best to you,
