You have not indicated in which State you are presently residing. Therefore I cannot tell you with certainty what the residency requirements are, which you will need for your State to accept jurisdiction over this divorce matter. It will not be necessary to return to be the Philippines to get your divorce. But it will be much more difficult if you cannot locate your spouse and serve her with the divorce papers. You should consider doing a person search that may be able to locate her in the US. An annulment may be a possibility, but you will have to prove fraud to succeed, which proof may be difficult for you to provide.
I suggest that you proceed for a regular divorce based on abandonment and make every effort to locate your spouse.
