Falling in Love with My Brother's Best Friend

I hate Lucas very much, even though he is my brother's best friend.
Everyone else looked at Lucas and saw a righteous gentleman. But all I looked at him and saw a malicious, self-righteous jerk.
I had proposed my feelings to him whom I had fallen in love with the moment I set my eyes on him.
However, he had crushed my feelings and went abroad the next day.
Now, he's back and undeniably, I couldn't believe that my heart still beats for the man who had crushed me so hard after several years.
Can I let go of the love I had for him or it seems like it has come to stay?
