Just because someone has a gorgeous heart and gentle nature doesn't mean they're naive or fragile. You don't know the type of chaos it took someone to be that calm. Never confuse kindness for weakness.
Those people have survived the hardest battles they are so smart and strong, and they are so intelligent to cover their wounds so nobody can see it because all they want people to see is their happiness side not hurting side.
So, if you find type of person like that in your life you should appreciate them and always try not to makes them to reveals their wounds to you because it might be sometimes you are not ready to accept it.
And you shouldn't ever thing kindness and sacrifice they made for you as a weakness and don't take it for granted because you will regret it and you might go to lose them you will never find someone is like them in your life.
And I am assured you they are strong enough to face whatever it is in their way but you know they are just human and their walls can break down and hold everything inside so look after your partner always and don't let them down.
