My sister and I are both in our 50's. We have always been close, holidaying together, days out, Christmas's together, looked after each other's children, pets etc, we've always been together. Our mum always reinforced the importance of family and we as a family, always stuck together. Our mum passed away last year and our sibling relationship has changed, on both sides. Neither of us have much inclination to invite each other to anything and we have quite quickly, drifted apart. It's almost as if our relationship died, when our mum died. It's not fair to blame anyone as I myself haven't been inviting her to things and she hasn't me, it's like an unspoken, mutual decision that we don't have to do everything together anymore. We haven't fallen out or argued. Has anyone else experienced anything like this?
