I don't know if it's "on purpose". But from what I read and see on here, it's certainly not uncommon. The WAS wants to keep that safety net in their back pocket JUST IN CASE the grass isn't really greener. You wouldn't jump out of an airplane without a parachute, right?
Look at your texts above. There was no need to reply to the first one at all! Did he ask you anything? Did he want anything? Was there anything urgent? All that text convo looks like to me is a small argument about nothing. About who gets the last word. Who gets to be "less the bad guy". Even though you didn't mean to, it comes across as controlling and irritating. So don't feed that fire!
