Definitely complicated. Something else that you might find if you compare this with this OP's previous 2 questions on IPS is how this OP seems to have asked 3 questions with very different backstories and circumstances, I wonder whether these events occured at different stages of their life @Jess K?

@EnglishStudent Huh, that's interesting. Not really a good way to tell though, unfortunately. Makes me wonder if maybe these interesting background events in their life could explain why they aren't more burdened by the concerning behavior of their partner listed in their question (most people would be more than just annoyed, and many of us were very concerned... enough to even close the question), but we aren't psychologists and that's out of scope for us to think about anyway so I won't indulge further, I suppose!

Note 2: I am not referring to this Q in particular but there were a series of meta posts around September whose consensus was that if a core character in a question needs professional help rather than an IPS solution then it is a reason to close the question, though "requires professional help" was never formally adopted as a custom close reason, so the Q would be closed using one of the available close reasons.

@EnglishStudent Thanks for the link, I'm going to peruse those. I guess my biggest concern with this one in particular is that OP doesn't seem mentally distressed by his girlfriend other than just annoyed... so wanting to talk to her doesn't seem like something he really needs professional help doing. Professional help seems like a consequence of OP continuing his relationship with someone who acts like that but isn't something that seems like a current reasonable solution.

@JessK. or he could just hang around until she murders him.

@RichardU You're a severely dramatic individual. There are plenty of people on this site who suffer from various social disorders and don't always act the healthiest in social scenarios. It doesn't give anyone a free pass to be a manipulative partner, but you're condemning someone you don't even know and that the OP just wanted to literally have a talk with ABOUT said manipulative behavior.

@JessK. Well, I could have you talk to my friend who went through the same thing, but you'd need a medium or a psychic to do so.

@RichardU Your personal experiences aren't a reason to deny someone the opportunity to find help in figuring out their own experiences. Not every unhealthy partner is a murderer.

I am not making an assessment for/against the possibility that "not OP but partner needs professional help more urgently than an IPS solution" - but that factor might've influenced the decision of members who voted to close, judging by answers here and certain comments. If so, the method to assess, based on those meta posts about 'professional help' is (a) if professional help for a core character is the definitive solution and if there is really no IPS solution to offer, vote to close. (b) If there is an IPS solution then write it as an answer and ask OP to seek expert help.

@EnglishStudent So could a valid answer not be "It might be better to have a talk with her about seeking help for her behavior, here's how you could try that..."?

It could be. That is really what the community should decide in the form of reopen voting, and you have raised enough attention for that through this meta question, which I therefore appreciate @Jess K.

@JessK. you don't tell someone to have a nice talk with a psychopath. To even suggest that having a chat with someone displaying behaviors that are such clear red flags is the height of irresponsibility.

@RichardU that's your personal assessment and if that's the case you shouldn't post an answer. It doesn't violate community standards and that's why I think your reasoning for closing is invalid. Our role is to help OP with OPs goal, not draw conclusions and decide OP is going to be murdered and close their question (which btw just denies them any reasonable discussion on framing different action they should consider).

@JessK. it's still too broad regardless.

@RichardU Our debate is honestly the exact reason a question shouldn't be closed only because "you'd feel liable". I see it as a worse thing that we would ignore giving someone a frame challenge, at least, to tell them to view their situation a bit differently and take different action with their relationship vs just talking, while you see it as something we shouldn't even touch. Sphennings answer below honestly has the most value into why this question is rightfully closed.

@RichardU You already said you wouldn't vote to reopen if the question was restructured so it's clear your personal biases are in effect, regardless of what state the question is in.

@JessK. is there a reason for these endless ad hominem attacks, or do you just have some bizarre need to bury your teeth in someone's neck today?

@RichardU I ended my conversation with you on your own answer and you invited yourself up here to interrupt a constructive commentary by inserting wild, off-base commentary about OP's girlfriend being a murderer, which is clearly because of your personal history. I don't know how else this conversation could've gone other than in indulging your own personal history.

@JessK. you are elevating rudeness to an artform

I was not involved in the closing, so I don't know why it was closed. I did vote against reopening it. There is a phrase in the question which alerts me to the strong possibility that this question should not be kept on this site. "I have a history of mental illness and suicide attempts" With that admitted history, I do not think it is responsible to become involved from a distance in providing any input, guidance, or suggestions other than "Seek professional help." Lacking a custom close reason to that effect, closing as too broad is a good second best choice.

@WitanapDanu That statement was only made to iterate potential reasons for a friend/SO to be intrusive or worried, not that OP is that way currently. If someone posted a question that said "I have a history of suicide attempts. How can I tell my coworker to stop asking me about my past?" should that also be an issue?

Not if the situation with the coworker is seemingly near-normal, at least. The scenario presented by the OP is not anywhere near normal. Context given should be considered, and the context of the question is serious enough to warrant a hand-off position in this environment.
