There is a simple surefire way to know. It applies to friendships, family, and relationships alike. Look for yourself in that person, and look for the impression you've made. In an honest connection two people rub off on each other. When one person doesn't understand the other, or take notice, or make any effort to, its a pretty good indication they don't care. You may think you mean something to someone, and not.

When introducing yourself to someone, you become a character in their mind. What happens more often then not in relationships is that people imagine the character developing with certain expectations. We tend to see the person we are looking for, and when reality sets in, some may find it isn't really what they were looking for. They become a character in your mind and you have to avoid making the same mistake.

Again, look for yourself within them. What is really terrible is when one person leaves a relationship and the other person genuinely cared, because now the personality traits of one person have rubbed off to another, while the person who didn't feel any real love is free to leave without any problem. No good deed goes unpunished, that is especially true when it comes to loving someone.

This situation leads to what Shamans have termed Soul loss, where parts of the souls can be stolen from someone and negative energy entities can attach themselves where the holes are. Where two become one flesh, things can get shifted around. Emotions, intellects, and spirits also blend. Keep in mind a relationship entails becomes one with another person, and like a pyramid, the more unique you are, or wealthy, or wise, the harder it is to find someone compatible. Becomes one with someone on a much lower energetic plane will actually bring you down, and not really help them.

Test the waters, and it should become clear who cares and who doesn't. What they done to you within themselves is an indication of where you stand. What then should you do to them within yourself? Be mindful there are many who will eventually betray you. Let them develop, but if you're a deep feeling person, tone it down. You don't want to find yourself craving the company of someone who betrays you. He who cares least controls the relationship.

As with driving, check to see whether the road is a dead end before you crash. A friendship is supposed to be a two way street. Be mindful of what is being done to you within the minds of others. Look for yourself in others. You may have made no impression to the shallow, who has not really taken you in, but if a deeper person takes them in, the experience becomes one of rape and trauma.
