Part 2 - Toxic relationships From my point of view, if trust issues are not the number one reason for toxic relationships, it has to be one of the leading causes. Trust is essential in a marriage or romantic relationship since it serves a foundation to build a feeling of safety and security. A healthy relationship cannot grow without trust. Sometimes, previous life experiences can severely affect our ability to trust in other people. Trust issues in a relationship can instigate fear, judgment can become clouded and doubts and suspicions may grow. People with lack of trust begin to constantly accuse their partner of being dishonest. They are always stalking their partner’s social media activities. They get really upset whenever their partner choose to go out without them. They want to be close to their boyfriend or girlfriend all the time because they feel it is the only way to really keep an eye on them. If you ask me, at this point, the relationship is far from being a bed of roses, but rather a nightmare.
