It honestly depends on the kind of love it is. But generally speaking, love can blind people. It can keep people from seeing the truth in others, as well as themselves. Say a woman is married to a husband that beats her. She loves him, of course, but she won't save herself because of it. Or maybe this is parents that beat their child. That child becomes just like their parents, or becomes an amazing person because of their experiences. It’s all about perception. Say you have a big presentation at work that you're extremely nervous. A person you love (and who loves you) could be there and comfort you and help prepare you. Love can be equally blinding as well as helpful in life.
