My younger sister is 24, I'm 28. We had a rough upbringing due to an abusive father, who left when I was 12. My sister has serious undiagnosed depression, which results in destructive behaviours. Two years ago she tried to sabotage my wedding and I've been unable to forgive her. Mainly because she is hugely selfish and takes no responsibility for her actions. She isn't a bad person, just very depressed and very selfish. She shows know care or interest for anyone else. We haven't spoken since my wedding day. She hasn't tried to speak to me and has blocked me on all social media.
Without any form of apology or attempt to rekindle our relationship I have no aspiration to involve her in the family I'm building with my husband. She despises children so I suspect she would have no interest anyway.
Should I tell her I'm pregnant? Should I tell her when the baby is born? Does she deserve to know? And if so, how should I tell her?
