Long term relationships will often become stale when the partners don't make the effort to keep the romance alive and well. They can go weeks, months and even years this way. There is a high level of comfort being with someone familiar. Knowing their habits and accommodating their needs becomes routine. Unfortunately, this often leads to divorce when people realize they must do the work necessary to rekindle the romance. Some believe it is just too much work and would rather leave the relationship. Others do the work of fanning the flames of romance only to completely blow them out.
Divorce is becoming more common as couples spend their energies on other facets of their lives. Many work long hours and forget there is even a person waiting at home for them. Some do make an effort at times to keep the romance going, but it is often not enough. They end up divorced because they didn't work at their relationship and their partner has moved on in life. This is the acceptable way out of a bad relationship in modern society.
Leaving a relationship may be easy or difficult. It depends upon the feelings of the partners. Divorce has become routine over the years, and couples are generally in agreement that they both want to end their time together. For those that are not yet ready for another relationship, a fuck buddy can be found online. Jumping right back in to a relationship is not always good for people. That is why fuck buddies exist. They help people take the time to explore relationship options without haste.
If a person already has a partner for no strings attached sex, it is easier to be patient when seeking a long term relationship. This gives them the space they need to make changes to their life. They will be able to focus on their new partner when they find them and begin a good long term relationship.
