I just don’t think that’s something that’s reasonable to by default expect people to be lying about, even if they are known not to be credible, and it definitely isn’t a detail that’s ever appropriate to omit entirely from coverage of someones death. If that’s the attitude towards it then getting away with “suiciding” someone in terms of public opinion has a pretty low barrier for success.
Otherwise you’d have to pay double the delivery fee or drive to two different places to pick up the orders, which might not be ready at the same time. There are advantages to cooperating on things.
If you aren’t doing things together, that’s a different sort of relationship than if you are. It’s valid to want one or the other, but should probably be on the same page about it with your partner.
To me most of the draw of a relationship, romantic or otherwise, is the opportunity to work together to make both of your lives better, to have someone you trust to care how you feel and who has your back, and who you can do the same for them. Playing a role in someones life can be a satisfying responsibility to fulfill and worthwhile, but it should ideally be something you actively choose to be responsible for. It sounds like what you’re struggling with is that because of your upbringing you have a hard time seeing that sort of responsibility as anything other than something that you get roped into due to circumstances, tradition, guilt and manipulation, but it doesn’t have to be like that. Sometimes someone asking you for help is because they trust you and know you want to help, rather than trying to take advantage and control you.
That said, you don’t have to want to work towards that either, it’s also fine if you want a sort of relationship where you keep a lot of distance from each other, just find someone who also wants that instead of someone hoping for something else.
