Be careful that "third party mentality" destroys your relationship
source
As for how to treat your boyfriend's ex girlfriend, this problem is actually a "fake problem". Unless you have to deal with your ex girlfriend, you really don't need to find a proper angle to "treat" it.
They regard their current predecessors as imaginary enemies and even worry that they will become the third party in the future. This kind of mentality is terrible. They seem to be worried that a third person will appear in their intimate relationship, but in fact they always regard themselves as the one who is not loved and can be replaced in their intimate relationship, which is called "third party mentality".
With a "third party mentality" to look at each other, to look at themselves, to look at the relationship between two people, and then find a variety of clues to verify their own views, eventually either there is a third party between you, or even if there is no third party, the relationship will become more and more loose, because you no longer see you and your partner as a whole, but just two parts separated.
The beginning of your embrace of this mentality is also the beginning of your rejection of your partner and the relationship.
As long as the other side is a little less than you want, you will feel that it is because of the imaginary enemy.
My husband came home late from work, maybe because he didn't want to go home to face you;
If I give you a gift during the festival, you will wonder if it is the style his ex girlfriend likes;
If it happens that your partner hasn't completely removed the photos, microblogs and contact information of your ex, it's definitely a composite preparation in advance.
You will enlarge a little disappointments to the height that he does not love you but loves the imaginary enemy.
You will also feel that, in this case, I will not pay, I will not work hard, you just want to wait for the "truth" to be pierced that day - he really told you that he did not love you in the morning.
As long as the "third party mentality" remains, the sense of crisis will overflow.
If you want to change this suspicious "third party mentality", you have to understand why you care about the ex, or even treat her as an imaginary enemy.
There's something wrong with your intimacy.
High desire for control, low sense of security.
Inferiority complex, excessive comparison.
The collapse of any relationship begins with two people. Even if there is a third party invasion, it's just an appearance. If you are not alert to this "third party mentality" and project two people's problems onto a third person, this is the beginning of a real crisis.
