You’re exactly who I’m writing for! In some ways, it’s sad when family members grow apart. But I think we should accept this as a normal process sometimes. Feeling guilty is never a good reason for trying to reconcile, and I think that guilt/pressure to do so comes from the way we’re taught to think about family. If anything, maybe you both need some distance. Of course, I’m no therapist. But coming to this realization helped me a lot.
