The quote that was often spoken to me in the middle of this discernment process of consecrated life versus married life is that 'our God is a God of joy'. There is a great sense of peace in moving toward the direction that God is calling you, and if He is calling you to be consecrated to Him, then that will be the joy of your heart.
The reason that some might be directing you toward the convent is that they see your desire for God and think (somewhat erroneously!) that those who are called to consecration somehow manifest it by a disciplined and devotional faith life. I think it might be a compliment in disguise, as it bespeaks that you have your 'spiritual house' in order for marriage.
Finally, while it seems that we can (and do) refuse God's will, I think that if you're really seeking Him, He will not let you go astray. He's good like that. :)
