Yes, you can sue him for civil assault. This is what you must prove by the greater weight of the evidence under TX law:
A person commits an assault/battery if the person:
(1) intentionally, knowingly, or recklessly causes bodily injury to another;
(2) intentionally or knowingly threatens another with imminent bodily injury; or
(3) intentionally or knowingly causes physical contact with another when the person knows or should reasonably believe that the other will regard the contact as offensive or provocative.
Hall v. Sonic Drive-In of Angleton, Inc., 177 S.W.3d 636, 649-50 (Tex.App.-Houston [1st Dist.] 2005, pet. denied). (citing Tex. Pen.Code Ann. § 22.01(a)).
It is not a defense to an assault and battery claim that no actual bodily injury was caused. All that is required is an invasion of anything closely related to the plaintiff's body. Further, A person who has a right to be present at the location where the force is used, who has not provoked the other person against whom the force is used, and who is not engaged in criminal activity at the time the force is used is not required to retreat before using self-defense force.
In a successful assault or battery suit, you can get damages for the injuries and expenses that resulted from the tort. That usually includes any medical expenses, lost wages, or pain and suffering that the victim experienced. If the assault or battery was especially traumatic, the plaintiff may receive damages to cover the cost of therapy as well. Victims of these intentional torts can receive a special type of damages known as punitive damages. Punitive damages are meant to penalize the defendant for especially appalling behavior and deter others from engaging in similar conduct.
