Libra knows they have found their perfect match when they FINALLY leave all their doubts behind when he can stop all his insecurities and questions.
There is no more "what if ...?" Now you are 100% sure that you want that person by your side in the future. With her, Libra has stopped worrying about their freedoms. Before, he was afraid of committing himself to someone and that that person would not be able to respect his freedom and his space.
Libra has always had problems in the past because they feared missing opportunities to be with that person, but now it is not like that.
You have already met someone who has made you understand what love is. You already know what it is to connect so much with a person that you cannot imagine a life without them.
Libra feels that the person who has been waiting for so long is in front of him when he knows that he is being valued as he deserves.
When they know how to listen to everything they have inside and out.
Also when it makes him control his impulses and reminds him to think a little more before acting if he does not want to regret it later.
Libra now feels at peace because he has found someone different. Someone who has that spark that makes him see things differently.
Someone who did not enter into Libra's plans because, even if he had no established canon, he has realized that that person has broken all the barriers that Libra had in place. Although it seemed Libra was not demanding, he was waiting for that person to leave him speechless. And so it has been because now he feels sure of himself and ready to take over the world.
