I haven't read all of this thread but what I have seems to be the biggest load of cobblers I've seen for some time (and I have seen some).
What sort of job do you have where you work 16 hour shifts? When Mrs NJ and I were both at work full time we parted at about 7am and returned home at about 6pm. During that time, unless there was an emergency, neither of us spoke to each other. Texting was not an option but even if it was I cannot imagine either of us having enough to text about for an hour a day. (As an aside, I cannot imagine either of our employers putting up with us doing so).
It seems you both have problems. To need to "speak" to each other that frequently shows a singular lack of security, imagination and a compulsion bordering on illness. Try giving up the texting. Spend your days apart and then talk to each other about the day (you know, in the old-fashioned way, with words coming out of your mouth) when you get home. You'll find it a lot more enjoyable than this ridiculous mania you are gripped in at the moment.
