Don't mistake a crush for love. Crushes are based on intense sexual attraction but they don't last. If you're lucky, a crush will lead to love but not always. Likewise, not all love affairs start with crushes, some are slow burners that catch you by surprise. You may find yourself falling in love with someone you didn't even find attractive the first time you met.
Love is more lasting than a crush.
It means that you accept a person with all their faults and their problems. You accept them for who they are unconditionally and want to support and help them. You'll just know. The British Association of Counselling can help you find an accredited counsellor near you.
