While this sounds simplistic, I find looking at all the evidence when there is drama and continually looping over it, exhausting. When I'm hyperfocused on someone else, I stop caring for myself (and sleepless nights make me less functional, and have made me sick. This only happens when I have a social conflict..... I revert to older behaviors from history with x-husband or narccistic family members and my fall back, when things are crazy is to rely on the duck.
I use my duck analogy for many life and social decisions. It also helps stop looping. It helps me arrive at the answer to the questions I have about other people with respect to a relationship with me....and my dreading taking positive actions to support my needs.
If it walks like a duck, and talks like a duck, and inside feels like you're pretty sure it's a duck (secure), then it is likely a duck and believe what you see....unless it stops/changes the way it walks, talks and feels in your gut-then there may be enough evidence to know that it's not a duck like you thought and now you have an issue to deal with. Usually things are as they appear if all 3 of these things are in sync.....but if you are paranoid and expecting to find wrongdoing then don't rely on the duck solution. Good luck!
