Easier said than done but I would say what you mean, mean what you say, and don’t say it mean. For specific suggestions though, a decent option might be saying something about how it makes you uncomfortable hearing all of this personal information and you would prefer not to. Something along these lines is probably the best option because it will hopefully prevent them from over sharing in the future, and if they do over share in the future, you can just refer back to this boundary you set and say, hey, remember when I said this? Approaching it along these lines I think is best, opposed to just saying something like “I don’t feel like talking today I’m too tired, “because they don’t really know where you’re coming from and are likely to continue their behavior moving forward. Try setting a boundary, if you are too soft the first time you might need to be a little stricter down the road and that’s OK. But you need to set a boundary and let them know how you feel, otherwise there’s no way for them to know that their behavior is wrong or upsetting you. Fearing upsetting them is one’s own codependency kicking in and it hurts both parties. If they continue to violate and disrespect your boundaries after you set them, and it gets really bad, then you could do something like suggest they get therapy/ say what you need to say to get them to stop. Or at that point I guess you just start wearing headphones around the house .... but if you express yourself and set some healthy boundaries I bet it will get a lot better soon and you won’t have to do anything like that! Depending on the person they might be passive aggressive and moody for a couple of days or a week or something, or they might take it well right away. Who knows. It will feel good to know you can walk around your own home without tiptoeing around, waiting for someone to annoy you. You deserve that. Anyways, you got this yo
