I am in a inlaw whatsapp group and one member, my sister in law, consistently ignores my posts/photos and gushes (and I mean gushes!) on everyone elses. It's like she is making an ingroup with the other members of the group and excluding me. I am nearly sure she is jealous of me for a number of reasons, mostly that we are well off, can afford holidays abroad etc. That is ok, I can understand that, she is very insecure. But I don't know how to deal with her posts/photos going forward.. Should I ignore/comment on hers? My husband says to keep being kind and stick to my values, not to let it upset me. But it's so mean spirited and I comment /like through gritted teeth. What would you do?
