Stages of a healthy dating relationship
The problem here is that as a couple you believe that arguments are bad but you are angry at each other anyway.
Conflict is not only avoided in this stage but seems like it will never happen at all. People who are constantly changing partners are often trying to remain in this stage.
Without strong communication, trust and the ability to work as a team, couples are unlikely to advance past this stage.
If a couple can navigate through the unstable waters of stage three, they will find that stage four offers much rest and enjoyment.
As a couple, you now have history together and you have been able to work through some differences.
The fantasy of stage one is completely gone, but you have accepted this.
