Think about your motives. Think about why you want to be in a relationship. If you only want a person to love you in order to feel better about losing another relationship or to make someone jealous, then getting that person to fall in love with you is a bad idea. This is inconsiderate towards the very real feelings they may end up developing. If you want someone to fall in love with you because you want to be with someone for a long time and have a mutually supportive relationship, then go ahead.
