Often
When someone else appears next to your person it lands hard — and not in thought but straight in the body: the evening is spoiled, the conversation won't run, and letting go isn't something you can decide to do. It is worth saying plainly what this doesn't mean. It is not weakness and it is not possessiveness: a strong reaction to a threat against something that matters is precisely what attachment is for, and in the research this side of jealousy tracks with love rather than with distrust. The real cost is elsewhere — in what the episodes themselves take out of you, which is invisible from outside and which you pay alone. What works here: of the three, this level has the lowest cost of saying so. You have nothing to prove and nothing to explain — "that got to me" is already a complete message.
Sometimes
It lands when it genuinely lands, and not over small things. Ordinary flirting in your partner's direction passes without trouble; something that looks more serious registers — and then lets go. This is where most people are, and it is a sensible setting: reacting to every signal is expensive and pointless, reacting to none means collecting no information at all. It is useful to know where your own line actually falls, because it rarely sits where you would say it does. What gives it away is usually not the size of the reaction but its length: the thing that really landed you will find still with you an hour later, and the thing that didn't ends when the moment does.
Rarely
Someone appearing next to your person doesn't land on you. Flirting in their direction passes by, other people's attention registers as a fact, warm words about someone else return nothing. Here more than anywhere else in this test it matters not to read a low level as a good result. The research says something that usually surprises people: it is the emotional side of jealousy that runs with love rather than against it — meaning a zero in this column is not a pure form of trust. Sometimes it is the steadiness of someone on solid ground; sometimes it is a cooling that hasn't been said out loud yet. A questionnaire will not tell those apart. You probably will.
