Just that, really. I wonder how common it is. I don’t mean thinking of them in a nosey way but when you think of someone and it pulls your heart a bit and makes you feel sad. I remember an ex bf said you never get over relationships, you just push them down and bury the feelings.
I think that was more a reflection on him maybe but I definitely do feel that with one relationship, as not great as it was, I still years on feel sad about it and wish for what could’ve been.
