If Leo's best friend cheats her, then Leo will be very sad, but Leo will not give up this relationship, because his heart is very fragile and soft for Leo. Leo will trust his friends very much. Even if he cheats him again, he will trust others. Leo is far from being as smart as he looks, but in fact he is a particularly simple person at heart. He thinks everything is so beautiful.
After someone has lied to her, he will always fantasize and give himself a hundred reasons for not deliberately lying to you, because Leo really cares about everyone who appears in his life. If you have a lioness girlfriend, you must cherish it and don't cheat him. Although she is willing to believe you once or twice, if you lie to her too much, I believe no one will believe you again. If you have a lion boyfriend, you must satisfy his love face and don't show that you lied to him in front of others.
Otherwise, he will be very angry. Even though he loves you very much, you still make him lose face. If your friend is a Leo, cherish it. As long as there is a Leo, he will always treat you well for a lifetime and his feelings will continue to deepen.
