Post discovery

I messaged mat today to inquire about what all had happened yesterday after his wife read our chat full of amorous exchanges of two days. He said all was okay. He elaborated that she read our chat and was upset that it was on an off day and that it was too open and frank. He simply told her it was with a colleague of his. He on the other hand was genuinely upset and irritated that she read it at all! Back in the beautiful days, I would always tell mat to close conversations on his phone. He always told me that no one touched his phone. Well there is a first time for everything. What intrigues me the most is that why did she if she hadn't until now. Something must have triggered her senses and I simply dont know what! Anyways, for future reference, I told mat to close his conversations to which he playfully replied "hahah :) of course :)" !.
