Which either suggests a) Jenny was in wrong or b) that Lindsay was in the wrong but she didn't expect Jenny to quit upon revelation of the wrong doing.She said tattle doesn’t really bother her (stuff about her parenting, her love life etc) but she was really annoyed at the response to them falling out.
And she has also blocked tattle
If it was option B, Lindsay must have been frustrated with Tattle if people were praising Jenny because it would feel like people were on Jennys side without even knowing the details.
