Thank you for your question.
Generally, USCIS recognizes common-law marriages in those states that recognize common-law marriages. For Texas, in order to be considered common-law married, you have to meet the requirements of Texas Family Code §2.401 for an "informal marriage". See http://www.statutes.legis.state.tx.us/Docs/FA/htm/FA.2.htm#2.401 for specific details. Of course, you and your boyfriend could also get married so that you have a formal marriage certificate.
Assuming that your boyfriend last entered the U.S. lawfully, and is not inadmissible to the United States (http://www.borderimmigrationlawyer.com/grounds-of-inadmissibility/), he may be eligible to apply for Adjustment of Status (green card). Please visit my site for additional detailed information: http://www.familytousa.com/green-card-through-marriage-ad/
If your husband did not last enter the U.S. lawfully, he may still be able to pursue a green card through another process - Immigrant Visa Processing. http://www.familytousa.com/immigrant-visa-processingconsu/
If your husband is inadmissible to the United States, he may need a waiver, assuming one is available.

Thank you. I wish you the best of luck.
