it's your life! Are you converting to Islam? You should!

Foolishheart, go for it 'cause the flame now is very much burning. The desire is already there and rather falling into an illegal affair, better make it legal and marry him. You will know the time when everything you're feeling now is right or wrong and if things really will not worked-out later, then in their religion there is a solution (which maybe hard but doable).

Just put one thing in your mind now, you'll marry this guy out of love and you need to sacrifice some things to make it worked.
