My sister is currently going through a separation and her and her partner are still on very amicable terms. Completely different story with her sister in law - she has been interfering and gossiping so much, which has in turn caused my sister and her husband a lot of upset. Even her own family are telling her to back off.
It was recently my Birthday and she got me a gift and a card. I really wasn't expecting one and now I feel obliged to return the favour, as it is her Birthday soon. I don't want to but my Mum has told me that I should. She has caused so much upset to my sister and her partner, I don't think she deserves a gift. Lol I could just return the one she gave me!
What would you do in this situation?
