ahh, he would've likely been so surprised by her level of transparency after the fact? yet another reason why he doesn't hold anything against her. enough time has passed, any confusion has since been addressed, and they're both adults, so...they can figure out ways to move on and be friendly. i love that she's trying to be intentional about this though! he's absolutely the guy who will still respond to texts/social messages from exes and actually carry on a conversation that goes past "how are you? good? okay." and won't really hesitate or find it odd to send random texts about something that reminds him of her or things he feels compelled to tell her. not...anything creepy, just like, "remember that guy who used to play the accordion on my corner? he moved up a block and now he also has a harmonica." things of that nature.
of course! he's a good guy with a good heart, they could've definitely supported each other the best way they knew how whenever they needed it.
