Have you ever left because you felt unwanted?

What do you think sama orang yang gampang move on? Semisal kalian punya hubungan 5 bulan, dan ex kalian itu cuma butuh seminggu buat move on sedangkan kalian sampe berminggu minggu atau berbulan bulan. Is that normal? I mean, gua selalu cepet move on karena prinsip gua kalo udah selesai yaudah, jangan liat ke belakang, tetep terus liat kedepan. But some of my friends said that was a little bit weird so, what do you guys think? Lemme hear your opinions.
