How to spend the bottleneck period or running-in period of feelings?

How to spend the bottleneck period and running-in period of feelings? Every couple will always have an initial love period in the process of communication, followed by a cooling-off period and a running-in period. If the bottleneck period and running-in period pass, your's relations will be stable; if it fails, your's relations will be shattered. So I think it is very important to spend this time in the bottleneck period and running-in period of feelings. During this time, there may be many contradictions between you two, but I think these contradictions are nothing more than trivial matters, indicating that nothing will happen after two people have been together for a long time. What you two need to do is to reduce the probability of this contradiction. Don't always quarrel over trifles. Don't always think that quarreling between you two won't threaten your feelings. In the bottleneck period and running-in period, there must always be one person who needs to take the initiative. Because two people quarrel, one person always needs to apologize to the other. I hope you got something. The person who keeps apologizing, when there is a problem between you two, you should look for your problem from yourself. Never choose to have a cold war with each other, because the cold war at this time will consume the feelings between you two, and some couples will break up with the cold war inexplicably. If there is a problem, solve it. The cold war is irresponsible for your feelings and for each other. Finally, I think if the bottleneck period and the running-in period are difficult for both of you, you might as well try them separately for a while. We always understand something after we have experienced something. I felt the same way when you were apart. You may remember how wonderful you were together. It's hard for you to live apart now. I think it's worthwhile if you take the time to be apart and let you know what is most precious to you.
