Love and Trust

A loving relationship is ideally the closest relationship two people can have with another person. Closeness means intimate knowledge. And intimate knowledge is dependent upon honesty, openness & communicativeness. For some people, lack of eloquence or lack of capacity for self-expression creates a barrier -- a barrier which is more forgivable than intent to conceil.
Open communication is a risky matter. People who have nothing they are ashamed-of in their live are more likely to be shameless liers & brutes than people of exemplary conduct. Telling deeds of misconduct to a beloved risks loss of trust and loss of love. Any person who can feel the riskiness of self-revelation for themselves can surely "cut some slack" in appreciating that their partner would have similar fear.
The situation is quite different, however, when evidence becomes undeniable of premeditated deception or theft. The ego & heart are wounded by such betrayal -- love can quickly turn to hate mixed with grief. A single revelation can suddenly illuminate a pattern of deception & manipulation through the whole history of the relationship -- and/or raise suspicions.
The desire to love entails a desire to believe in the lovability of the beloved. Love can easily be blind -- facts are interpreted through the "rose-colored glasses" of wishful thinking. Denial of facts may continue for a remarkably long time -- sometimes indefinitely. Hopes, dreams & plans are not easily relinquished. Remorse by the offender and forgiveness by the victim can sometimes lead to redemption -- but this is more often the exception than the rule.
Others -- especially those with a history of having been betrayed -- may err in the opposite direction. Incessant suspicion, distrust and resentment associated with imagined betrayals can poison the possibilities for love. Pre-emptive, self-protective disbelief in the trustworthiness of a prospective partner can destroy the potential for a relationship. (The same can be said for a suspicious ego that pre-emptively resents and/or rejects a potential lover on grounds that love might not be reciprocated.)
Trust can be violated by failures of competence -- such as forgetfulness or clumsiness -- as well as by conscious deception or betrayal. Although it is easier to forgive good intentions, any source of predictable lack of dependability undermines trust. It is normal that people love their children without trusting in their children's competence (or good judgement or even integrity). Some people have the capacity to love without trust of any kind. Whether such people are big-hearted or foolish cannot be answered
objectively -- it is a subjective matter. unconditional love can be a warm security blanket, but it is also not a tribute to lovability or worth. Love that does not discriminate good from "evil" is an undeserved reward.
