Cusp signs in relationships are not so different than their base signs. If a person is born under the sign of libra on the first day of the libra sign, that person will have libra characteristics but with some virgo elements too. If a libra is usually undecided and has a hard time dealing with tough decisions, the fact that that person was born on the first day of the sign could mean that this particular libra is more decisive in taking decisions. Also a libra likes going out and being around people all the time, but in combination with a virgo , this particular libra wants to spend more time at home.
Cusp signs in relationships are not so different than an ordinary sign. Usually these characteristics don`t influence us so much. There are people who believe in the horoscope and people who think it`s just a silly way of complicating our lives. Sign characteristics are not very clear at most of us. Some people are totally opposite from what their sign says that`s why, cusp signs are not so different from normal signs.
Cusp signs in relationship can be more surprising than normal signs. For example you would expect from an aries to be very heardheaded but if he is influenced by pisces then he is more outgoing and tends to accept other ideas too. This influence is most of the times very good. Every sign has it`s flaws and qualities it depend which of these two, a cusp sign takes from the other. Some combinations can be more bad than the base sign, but people have their own character and their zodiac sign is not all that matters. The sign we were born under is just a way to identify us, not a way to characterise us.
If the sign says awful things about your character this doesn`t mean that you are necessarily like this. The horoscope is just a way to pass the time. It shouldn`t be a guide in life or in relationships. Sure we all know little details about every sign but we don`t keep in mind that a certain sign is not good for us. Judging people after their sign is not good because we can`t all fit to the horoscopes predictions.
