Again, I can only speak for my own situation. What makes a person seem 'safe', to me, is getting to the point where they seem to be predictable and they seem to be willing to accept me as I am in the moment, even if they don't understand it. Not try to change, not ask for explanations, just accept. Personally, as long as they don't blow up and tell me I'm 'wrong', I WANT to know how they're thinking in feeling. Best case, if I was involved with someone who had anxiety issues, I'd WANT to know how my behavior affected them. Probably not when it seemed like the rest of the world was falling apart, but I'd WANT to be able to talk about this stuff when the stress level is low. And then to make plans for what would work when the stress level isn't low. But, I tend to be willing to deal with stuff that way. Not everyone feels comfortable with that.
But, yeah, avoiding asking for hard to keep promises would be awesome, at least for me. Especially when things aren't good. Which, BTW, doesn't mean that the desire for a future isn't there.
Have you read the "Stress Cup" thing on this site? If you haven't, do a search, you might find it pretty helpful.
