I knew a friend who lost her father when she was around 12 but she never really talked to me about that experience. She has had several bfs since and she’s studying in an alright university. When I only mention my dad (e. g. saying he will pick me up) I can tell she gets slightly uncomfortable. I feel like she hasn’t moved on and trying to fill the gap with other men. Not trying to sound callous but I’m just making an observation.
