You two had an extended argument because you were out of contact for half a day? That's ridiculous. First of all, if he's a truck driver, why the hell is he texting all day? That's seriously dangerous. Secondly, when you're at work, you have a job to do. Contact during down time is fine, but the idea that he has to keep tabs on you to the point of when you use the restroom is seriously controlling.
