People who have been isolated with only one person find their sense of self has been diminished, and they often have issues when reintegrating into society. Their former partner would have damaged their view of the world by telling them constantly how other people did not like them, or they might have constantly told them how wrong they were about everything. Overcoming a lack of confidence in their view of the world and others is difficult, and a person living without a partner must learn how to interpret the world on their own again.
Confidence is necessary to be successful socially, and it is the basis of what a person in this situation must gain before they can go out into the world again. Many of them are forced to go out before they are ready because they need to earn a living, but they can consider their situation as just a way to pass time as they recover. Making friends at a new job is always nice, but it is not necessary when recovery is more important.
There are many steps that can be taken to regain a sense of worth, and finding local support groups can help. Reconnecting with family and old friends might be the answer, but they should be avoided if they become obnoxious with their opinions about the former relationship. Support and help with finding a way to regain self-esteem are more important than reconnecting at this time.
Few people come out of an isolating relationship without some damage, and it is important to discover how much has been done before entering new relationships. A person can recover completely, but they need to be selfish and take time for a full recovery. Once they have found their own emotional feet and have more confidence, they do have the chance to get into a good relationship that can last a lifetime.
