There are many reasons for a perfectly fine relationship to end abruptly.
If it has happened to you then you may be here trying to figure out the reason behind it.
Chances are you probably should not have been as blindsided by it as you are, simply because you may have been able to see it coming if you had known what to look for.
Think back to when you first met your ex and decided to start dating.
Is the only reason it happened due simply to a physical attraction to one another? If this is the case than you may have not noticed right away that you really had nothing in common with each other right off the start.
If you do not have anything in common a relationship can get old fast.
Without anything to do to occupy yourselves when you are together, you will get bored of each other in due time.
Simply admiring each other's beauty is not the only thing you need in a relationship, in fact you cannot even begin to build a relationship on looks alone.
While you may have started out with a lot in common, as you grow up and get older those interests could change.
If one person stops liking something and yet the other doesn't, you can have a clash of interests that will lead you to think that the other person just isn't growing up or maturing.
You have to be able to work things out and make compromises, but you also need to be able to grow together.
Relationships that are between two people that have just grown apart we never going to work out anyway.
With all of this said, it is important that you think about why you broke up and if it is going to work out when you try to get back together.
