Why Is Love Very Complicated or Blind??

Many people in this world say that "love is complicated" or "love is blind". For me love is both complicated and blind. Maybe for some people that have met their soulmate, they are very happy with that love, but even they are soulmate and they love each other very much, they must had gone through lots of trouble which is sometimes very complicated and lead to divorce or breaking up between a couple. That is why i call love is complicated. Now about "love is blind". This term, is very true. Many people will do anything to meet their love, they can even spend so much money in order to keep a love relationship. They will also want to do anything what his/her girlfriend/boyfriend wants. Why are they doing this? Why do they want to spend so much money for his/her girlfriend/boyfriend? The answer is only one, they want to make their soulmate happy, and with that happiness a love can last long even forever. But there are some couples who don't need money or treasures for their love-relationship, so they accept anything what are provided by his/her girlfriend/boyfriend or what his/her girlfriend/boyfriend has. This is only my opinion and there are no offends. Thank you ^^V
