In the case of loving someone, Don't trust them to never hurt you, Trust them enough to know that they are only human and they are bound to err.. Trust them enough to give them freedom and space, Trust them enough to know that their human nature can sin in anyway possible, Trust isn't about perfection, Its about knowing and accepting the fact that someone can sin against you or even hurt you but you choose to take the risk because you know that they are worth it, Don't make trust a burden for anyone, Trust simply and love truly..
Trust really isn't anything close to perfection,its just love being willing to get hurt cause it would be worth it.
