Relationships and Interactions fall into place based on mutual interest, the level that people mutually care about each other, and the mutual effort & responsibility that is needed to be involved and stay involved. Relationships are much like Gardens. I would hate to see someone's plants the way that they actually treat each other & expect their feelings to grow?~ Fortunately, we all have own responsible choices to make about our own personal lives.
Obviously, when there isn't anything motivating a Chemistry between people, or the Chemistry is not as strong, there isn't much of an Attraction if any at all. Some experiments fail, and some grow into healthy relationships.
Finding OUT is essential, otherwise it is a mute point to believe that you can take this other person's life personally as if you are actually involved with them in some delusional way. The person that is preoccupying your mind that ISN'T apart of your life is NOT preoccupying THEIR mind with the same ideas of closeness that you never make understood!
There is nothing Evil, or Wrong in coming to realize that you may not have the same Chemistry between you and random people that cross your path along the way of Life. Everyone initially should have a much more important purpose overall than to be #1 in some random person's life (or it isn't coming from a position of confidence or stability).
There is ALSO nothing Evil, or Wrong with someone that decides NOT to have closer relationships with those that they do not trust more, or feel comfortable with. When interacting with others on various levels of sociability, it is similar to opting-in or opting-out in advertising. Some people are even giving a message of NO SOLICITING! This doesn't necessarily mean that they are bad people, or that they do not LIKE PEOPLE, they are just more careful with whom they decide to MEET, involve themselves with and develop close RELATIONSHIPS with. When someone opts-out, it may be a disappointment but they are telling you something about mutual comfort levels. Is this someone that you would feel comfortable growing to know more? They may be better for someone else to be involved with more comfortably.
It is unrealistic to walk around and believe everyone is going to love you or like you at the same levels as your friends & loved ones. There usually is a REASON that people interact with each other, and that is why there is interaction & communication going ON but its usually understood mutually. Networking, participation in social events usually bring people together with the same things in common. If people are not open to communication 2 ways, this means that you do not have Chemistry with them, not that they are anti-social or do not like people! Making a genuine effort & FINDING OUT is the best way to get the results of your Chemistry with others that may have the same interests, which is the reason they are usually there!
No one is going to "like" you more than you like them; no one is going to love you more than you cultivate mutually, no one is going to sacrifice or compromise more for you than you do for someone else. Those things come with time, trust, understanding and more intimacy.
It is possible to generally tolerate others that are not best "friends", participate & coexist, and have a social conscience in that you don't like to see people harmed along the way (unless they put you at risk) - but it isn't possible to have the same level of comfort, trust, and friendship as you do with your relationships you've made.
It takes mutual genuine interest, care & concern and effort to be involved and stay in touch with each other. People usually understand how much they care, how much they are truly interested in each other, and how much of a part of each other's life they really are when they are more on a personal level with that person.
