Perhaps it's best to not form a relationship outside of work with this person?

The only way any relationship can truly work is if their is love involved from both parties. Otherwise, one person or both is just using the other. How do you know if it's a worthwhile pursuit?

Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. Love does not delight in evil but rejoices with the truth. It always protects, always trusts, always hopes, always perseveres.
