Is it possible to fall in love with the wrong person?

I never thought it was... but apparently it is possible to love the wrong person. I fell in love with the most amazing man, perfect for me in every way, no one could ever be better, my best friend... yet our passions are leading us in two different directions in our lives. We were planning on getting married... he even had the ring... yet, when I prayed about it I knew what I had to do. The hardest thing I've ever done. But I had to choose God over the man that I love over the only person I have ever wanted to and can ever see myself spending the rest of my life with. I love him so much... with all my heart... But I know it's not right. And staying together would make us compromise where God has called us... I have a heart for the world and I want to serve God on the missions field, he doesn't... he has a heart for youth ministry...

Y... I don't understand... I just don't understand why God would bring this perfect man into my life and let me fall in love with him just to take him away.
I never knew that I could fall in love with the wrong person.
