Dear Dr. Love:My problem may seem like a cliche to you. But it is tearing me up inside, nonetheless. I am in a very happy relationship with a man. We have lived together for six years, we have a baby together.The problem is, for the past 6 years, I have had a HUGE crush on his brother. Its like I am obsessed with him. I think of him all day and all night. Ever time I make love to my man, I think of him. I drive by where he works, I think up lame excuses to drive by his house. I have never told the brother how I feel. He is married. Im sure he wouldnt mind a quick fling. But I am concerned with the repercussions.My question to you is: Do you think that if I were to sleep with him just once, I could get over this obsession?Sincerely, Confused
