Do You Love Someone Who Doesn't Love You Back?

Did he tell you that he loved you and committed himself/herself to you but now it's all gone? What makes a person want to hurt someone else? I don't think it's intentional, but things happen sometimes that are out of our control. I knew that he loved me when we got together, and the happiness that we shared was real. We had a beautiful daughter and we were joyous ! Somewhere he must have felt that it just wasn't enough, because he chose to seek someone out and carry on with another woman. This did not last a short while, but a very long one. She must have just been waiting for every chance that she could get with him and she did not care that he was married or had a child. Did I still love him even though he hurt me tragically? Yes, I did, and he told me that he loved me too, but how could he have? Was I in love all that time with a man who only tolerated me because it was easy for him to let me be his housekeeper and business care-taker? Did he actually ever love me? I think at some point, he did, but why he chose to "love" or "lust" someone else is still a mystery to me, and I think it will always stay a mystery.
