My partner was married before we met. They were only married for about 6 months before it ended and she moved back to her home country (NZ). He's always been quite cagey about the actual reasons it ended, just says it didn't work out. This was around 20 years ago.
I know they are still facebook friends, and that they send birthday and Christmas messages to each other.
A few days ago, some magazine thing arrived in the post. I asked him what it was, and he said it was something the ex wife had mentioned, so he got it for her.
Earlier in the year, she sent him a pack of playing cards with Bob Ross on them, because he had been watching the painting programme on TV.
Would this feel weird to you? I seems so small and innocuous, so I can't tell if I'm just being petty by feeling uncomfortable. It makes me think they message each other more than just birthdays and Christmas, that they talk more than he's admitting.
