Time to give up now

If someone doesn’t care us, should we pay all our attention on him?
If someone doesn’t cheats us just like a common person, should we just want to stay with him?
If someone always makes mistakes, such as dating with another girls, should we forgive him from time to time?
No, we should not.
Just leave him. We are just a small tomato in his eyes.
Yeah, leave them as quickly as we can..
We will meet the other cheats us like an apple in his hand.
