I’ve had a friend for 7+ years (we’re both mid 20s) and they have a half sister who they get into fights with about once every 2 months. The half sister has physically assaulted them and anytime they get into a fight the sister says the most degrading stuff to them (calling them fat, ugly, a loser). My friend comes to me every single time and cries/vents to me about it and says they’re officially done with the sister and that they crossed the line. I love my friends, I have zero problem with being there for them. The most recent fight was last month where the sister called the police on my friend and made a false report. My friend told me that was the final straw and they would never put themselves into that situation again.

Yesterday, my friend told me they were working until 9pm. My aunt texts me and tells me they saw my friend grocery shopping around 5pm and said hi to them. When I asked who they were with, my aunt gave me a description of the sister. I texted my friend and just said my aunt said she ran into you grocery shopping. My friend never responded. I’m assuming it’s because they lied to me about the time they’re off from work and the fact that they were with their sister again. I’m really upset that they would do this especially after the incident with their sister last month. I’m also really upset because there have been times where my friend has ghosted me for months after being upset at me for the most ridiculous things but they constantly have grace for a half sibling that they weren’t even raised with. I say this because I feel like there’s a different bond between siblings with the same parents who were raised in the same household vs siblings with different moms who were never around each other.
