As human beings, we naturally crave social interaction. Whether you're introverted or extroverted, we all need interactions with one another. It is essential for our growth as individuals, growth in our societies and communities, and for forming friendships and relationships. The interactions that take place in a relationship are different from any other interactions, and sometimes, it’s better off that way.
However, occasionally, there are those relationships you wish had never had started in the first place. Whether it is just being too clingy and attached, moving too fast in a relationship, other people coming into play, or for any other negative reason, sometimes a relationship will just not work.
For example, if you have an ex that got very attached to you way too soon, you’re better off just moving to a different state.
Speaking from personal experience, the time that your ex is trying to win you back is not a glorious time. Moodiness and mood swings happen every day of the month. If you do not choose your words carefully, then they will instantly be upset and be mad at you. They will not want to talk to you for about a day or two. Then one of you will try to apologize, everything will be okay for three to four days, and the cycle will start all over again.
If things just simply moved too fast and things did not work out, it is not the end of the world or any need to panic. There could be another chance to make things work. If things did not end in an unpleasant manner, and you and the person are on decent terms with another, there could always be a next time.
If other people came into play, there isn’t the best chance of another good relationship coming with that person. Even something as small as jealous people starting rumors could affect your relationship - even if the rumors aren’t believed, they can change of how you think about or look at the person you are with. Or vice versa. If a relationship comes with another person, while already with someone else, you simply should not be in any relationship. Being cheated on can linger with someone for a very long time, causing additional problems in their everyday lives.
Depending on the situation, just because you had a relationship that didn't work out doesn't necessarily mean you will never be on good terms with that person again. A basic friendship could potentially come from the relationship. In fact, one of my best friends is also an ex. Anybody can become friends with an ex of theirs if they can manage to get through and put aside the past they share for the better of the future. It is not the easiest thing to do - you can ask my best friend herself and she’ll say the exact same thing, but an amazing friendship is worth it all, even if it is with an ex.
