No I don't think it's important to tell them about everyone a listing or affecting your present that you know like any trauma that might come up because of a person or any person to keep popping up but if you're gonna snow do it now then oh well
I don't think it's exactly necessary to tell anybody. If that person is still in your life and you still interact with them, you know, maybe it'd be nice to let your significant other know, But regardless, you don't have to tell anybody shit.
Honestly I think it's just important that if they ask you're open and honest about it and some things are better left unsaid but you know if they have a right to know if they need like reassurance or some thing
I don't think it's necessarily important like I don't think it's like a red flag if they don't necessarily but I think just as a couple things come up in memories and stories and so therefore it brings out more of their past
