I think my friends are toxic lowk

So the reason I say this is cus I’ve been talking to a newish friend recently and she’s awesome!! And it’s like a completely healthy friendship we communicate well and we vent a lot while feeling safe, and that made me realize some things my other 2 friends have done that aren’t the best- I know it’s accidental cus they don’t communicate well and have bad lore n stuff so it doesn’t bother me I just think I need boundaries. Okayy anyways PEACEEE
