Converting to Islam in a mariage or love issue isn't a faith, but Islam is submission, and submission is a way of life and responsibility. Absolutely accepting Islam is the most precious gift that one is received.
another thing is that guidance can't be obtained neither from science not mystical experience, so consult with your local Imams, i hope that your life should be a succesfull one, and you are fortunate one as well since all your sins will be washed away.

May Allah keep us with Islam.

Life is a school, people are students and the days are teachers.
