Rejected with 3.04 and 161 is somewhat understandable due to the low GPA, but 158/3.8? The Admission Com. probably thought "why would this Texan applicant want to attend here when he can get into and attend UH and Texas Tech?" Unless you have a reason to want to stay in OK, such as a spouse getting a permenant job there, etc. there is going to be doubt as to why you want to attend a schook in OK where there are fewer cities and job opportunities compare to TX where it has Dallas, Houston, Austin, San Antonio, etc.
