6. “Let’s stay good friends.”
“I might consider calling him once in a while.” Unfortunately, your Japanese girlfriend wanted to end the relationship. You are mature and have no hurt feelings, so you suggest staying good friends with her. That sounds fine, except if she has even the slightest regret about breaking up with you, your suggestion to stay friends may tie her down and prevent her from moving on with her life. If you suspect that she is somewhat reluctant to break up, refrain from making such a suggestive comment.
