Should I give up?

No, the road of life is your own. People who give up without fighting are the lowest.

If this happens to me, maybe most people will shrink back because they have no confidence and want to make her happy.

But this is not what smart people should do. If you really love her, don't give up. Maybe you have a chance.

Don't regret it in the future, even if you failed, at least you tried your best to win it.

Don't be afraid of losing face or something, because if she even isolates you, then she is not a good girl.
