Found a text on DH iphone, not snooping it had popped up on front page.
"How r u? Last night was fun x"
From a number not in his phone.
He was at home with me last night, not sure what to make of it. Wrong number? I haven't mentioned it and he has gone off to work without saying anything about it. If it was me, I would have said, "how weird, I just got a random text " or similar.
