Is love REALLY blind?

There were this discussion lately that people are "blind" when they are in love/relationship.

Are we really "blind" when it comes to relationship? I guess we are in some ways.

There are a lot of things that other people could see that has gone wrong and we (in a relationship who are blind folded at the time) surprisingly could not see them coming at all. I have read someone's blog about how married couples tried to get "sidetrack" with their relationship. 

I have got three perfect examples here on how they got blinded by the relationship. 

Scenario 1:

Joe and her bf stayed together for 6 years. They have known each other since high school. They thought they were going to get married. They have always been arguing about alot over ANYTHING. Things got worst last year when he locked her in her house and left. It was horrible. Joe rang us crying and asked for our help. Without a word we got to her place and found her crying and locked in her own house. Her passport, purse and keys have been taken by the bf. I was worried about her and thought of what had happened to me. We did not ask what happened and all we could think of was to get her out of there, away from her bf. W got her out at the end. Anyway, to cut this short, she went back to him despite what he did to her. 

Things got sour between them after a few months, when Joe discovered that she has feeling for another man. They ended the relationship. I mean she could have seen that coming. I mean when they gone nuts and did something that is harmful to you, you should get out fast! Do not hesitate! I think she was blinded by him at the time. 

Their second problem immersed. She got a personal loan for him to buy a car and he pays her back monthly. He stopped the payment after they have broken up and she couldn't do anything to him because the loan was under her name. Sigh... again she was blinded by him.

Scenario 2:

Jane got involved with a married man. I would never have thought that she could end up being the "third" party. 

She said that he was unhappy in his current marriage and that he was going to leave his wife. It is just that for the sake of the kids they would stay for a bit longer till the baby gets older. Jane bought that and fell for him. She waited for 3 years and got herself pregnant with his baby. Jane demanded him to leave his wife and et married with Jane. His excuse was he could not bare to leave the wife because she has no where to go and that he does not want to be the heartless beast. Again, she bought that and became his mistress. 

They have been together for 5 years now. She has been his mistress for that long and the wife or family doe not know about Jane's existence. I am not sure what Jane's children going to think about her decision. *Sigh* she is totally blind folded....

How could love be so powerful? How could it trick us so easily? I seriously think it is so powerful that it drives you to the edge and it is often out of your control.
