My half-sister is getting married. She's my sister via my mum (who I haven't lived with since i was 12) and her husband.
I've been NC with my mother for 10 years and my dhsis was young enough just to go along with my mum. There have been a couple of extended family situations since then, when our mother is there dhsis blanks me, when our mother isn't about we've chatted and she's enjoyed being with my dc (who our mother also blanks - which they found very distressing).
Now obviously We're not invited to the wedding, but I'm not sure what to do. I can easily get dhsis address from our brother (who is low contact with mother but invited to the wedding).
I thought of sending her a card and a voucher, and just saying we wish her all the best.
Am I mad?
