My SIL has to always one up me or prove she’s stronger, smarter etc. I withdrew from her in past which escalated in us ignoring each other and we had to clear the air. She apologised. Now, looks like she’s picking up the exact same habits- digs, demeaning comments like “you’re probably too weak to slap hard in this game” or her speaking in Spanish the whole time at a family gathering where she’s the relative with the best English and her boyfriend is British so no reason to speak Spanish around me when my Spanish is basic.

My question here is- from experience, what has to happen for this to stop? There have been conversations with my husband and her and then me 1-1 with her. When will this change?
