Trying to make my way out of the pits of heartbreak so lets hear some other red flag stories that you minimised / didnt realise until way too late. Let's save each other!
Mine
Did not really meet any of his friends / family
Only met an uncle when we were out randomly for drinks
Phone often on silent and never out of his reach
Never took photos of the two of us.
Would not connect phone to my car for mapping. Preferred to use an awkward phone holder
(Friend said later this was due to last seen destinations? I didnt know this was a thng but he worked in.comms)
Never used to see him on a Sunday. Now presume sunday was date night with whoever else he was seeing.
Always caused an argument if we were due to go away. I didnt see this pattern until way too late.
