The problem that you have is that they were ear-marked as gifts and he lied about their use. As such, it will be hard for law enforcement and the DA to show that it was a theft, that he procured the money from you by threat or deception with the intent of permanently depriving you of it. It is "possible." However, as a former economic crime district attorney, these cases are extremely hard to prove. You can hire an attorney and sue him for the reimbursement based on theft and coercion and there is a lower standard of proof in criminal cases.

I think that what you have described could be considered theft by deception and you should file a police report. However, as Mr. Leroi notes, these types of cases are not easy to prosecute and not very high priority for prosecutors.
You can also file a civil complaint. Your beau is guilty of making false statements on which you relied to your detriment - this constitutes fraud. You can sue and get a civil judgment. Once you have a judgment, you will have to figure out how to collect. If he has significant assets or a stable job then you may be able to get your money back. If he simply gets by swindling women on the internet, it may be more difficult to get your money back.
