It’s generally the mil taking this stuff. Interesting it’s his sister. You know you need to set some boundaries and stop going to places where she will be.

Don't have her come to your house, period.

It's time to end the relationship. Things won't change.

I think you should tell her that if she ever takes anything from you ever again, you will tell her parents (keep a running list). And suggest that if there's something wrong in her life that she needs to talk to someone about, her college probably has a mental health help center, or she can ask for a therapist.

You should drop him

He will probably be caring for her when she gets old

Have you spoken directly to her about it?

She's probably got some sort of problem...really selfish, a klepto, envies you, etc.

I don't think it's totally your boyfriend's issue because you are treating her like a friend.

One end run might be to ask their mother about it.

If she doesn't stop, don't do things with her anymore.

WHAT? What is NOT OK. My daughter takes my stuff just like I took stuff from my mother, but this is tolerated good-humoredly in our family. She would never take stuff without permission from anyone else.

I think you need to move on from this relationship and tell him exactly why.

If you can’t muster up the backbone to say “Joanna, don’t take or borrow and of my things.” Then yes, break up. +1

This is a thing for GenZ. They just see stuff as communal.
