First of all, Sagittarius
When it comes to who is the most love rat among the twelve constellations, the first thing I want to mention is Sagittarius boys. Sagittarius boys naturally yearn for freedom and are very bohemian. When you associate with them, you have no idea what they think. They are always changing. Emotionally, Sagittarius boys always love each other, like to have an affair with many girls, and don't really want to pay for them. As long as they can solve it with money, it seems nothing to them.
Second, Aquarius
Aquarius boys are more likely to hide their inner thoughts, and it often takes a period of deliberation before they finally abandon their other half. In fact, you may look at Aquarius honestly on the surface, but it is not, because they often disguise themselves. I think it's terrible because you don't like each other anymore, but you keep pestering each other and wasting each other's time.
I hope my answer is helpful to you! What do other friends think?
