Hi Zemi,
That is not a silly question.

Did I like the girl? Yes, but not as much as what God has in store for me. To use a simple comparison: imagine you know some girl who is really attractive, intelligent, has all the human qualities etc. but then you meet another girl who is a thousand times more attractive (if that would somehow be possible

), who shares your interests and has so much more to offer etc. If you would start dating with one of the two girls you would probably choose the second. Who wouldn’t? Well, I feel I have met this “second girl”, it is the Bride of Christ, the Church, for whom Christ gave his life.
The most tangible joy a man and a woman will ever experience in marriage depends on this: perfect mutual self-giving. Well, if Christ is calling me to be one of his priests then this total self-surrender to His holy will and to his Bride, the Church, is a pledge of overflowing joy… and of real Love: as you offer up your whole life for the good of the souls you will experience that “there is no greater love than lay down one’s life for one’s friends”.
Having said this: it is a pure gift from God, Who is Love. He is my creator and knows what is good for me. I trust that doing His will will make me the most happy man in the world (and that not doing His will will not). He keeps his promises! (Holy priests are the most happy people I know)
