I am wanting a divorce for some time, he got deported and I haven't heard from him since,what needs to be done?

There is nothing stopping you from seeking a divorce other than the ability to hire an attorney and/or pay the filing fees. You ought to seek help from an family/divorce attorney. If you successfully petitioned him, then his deportation likely ended your responsibility for him based upon form I-864.  He can be served at his last known address whether in the U.S. or outside the U.S.  If that does not work, then likely by publication, but you must speak with an attorney licensed in Texas to seek legal advice for that matter.  Good luck. The above is general information, not legal advice, and does not create an attorney client relationship.
