I should have said how I know about these. The first time a very similar message appeared (December) we were sitting on the coach and she sort of made like she didn;t want me to see, but later showed me. This time she sent me out with the kids and handed me her phone instead of mine, when I scanned to see "my" messages I saw the subject line "Thinking of You...." and who it was from. And yes, I opened it. That last part I guess wou;d be snooping. I try really hard not to spy.
If I ask her about this she will almost certainly start hiding her phone and being careful not to say anything.....whatever might be going on would go underground.
I don;t know if boss was alone when he sent the message or not.
W went to bed saying she was tired, we haven't been connecting since we had a conversation yesterday about future plans and schedules.
