You can't say that Libras are pretending just because they have another side, which is unfair to them, because many Libras don't realize that they are not a good gentleman or a good lady at all when they are young. They haven't figured out how to deal with the chaos and panic in their nature, so they just treat it gently and peacefully, hiding the pressure. As long as you stay in Libra's shallow corner of making friends, they will give you the best experience of making friends. But if you have a deeper relationship with Libra and discuss some deep-seated issues, their inhumanity will be exposed, but this is the essence of Libra, that is, I want to be rational and fair.
To be honest, it's really hard to get into Libra's heart. If you ask most Librans who they really care about? Maybe the answer is that no one cares too much except family. But there is also a bright side. If you have been in love with a Libra for a long time, he has classified you as a family. He really won't break up with you easily, nor will he give up your relationship easily. Most Libras are emotional partners. They won't make any demands on your relationship. Even if you don't have a good relationship with your partner, you don't want to be the one who breaks up on your own initiative, and try to keep the surface calm. But when anxiety and panic accumulate to a certain extent, they will erupt, and Libra will show indifference.
