Negative thoughts and emotions can cause us to behave irrationally. When we let our feelings reach a breaking point we can react in ways that are very damaging to our relationships. If we have had issues in past relationships it can cause us to bring that baggage into our current relationship. (Which never has a positive effect.) Our negative thoughts and feelings can get the better of us and bring out the worst of us. Don't let your negative thoughts and emotions sabatage your current and future relationships. When you are in a spiritually connected relationship, your emotions and thoughts are extremely hightened, and it is new territory that that if often frightening and overwhelming at times. This can bring out our deepest fears, and if we act on them, we can cause damage to our spiritually connected relationships.
