When you love someone a lot, you do not want to hurt them. Good principle, but a meaningful relationship is not possible if pain is not shared or understood. In fact, a problem or trouble in a relation can be a perfect ground for better growth/bonding depending on how quickly you resolve that problem. If a difficulty or problem is tucked safely without addressing it by acts such as avoiding to talk about it, blaming the situation or acting as if everything is going on fine, that will only be a short term solution. Troubles in a relation always accumulate and have cumulative effect hurting the relationship the most. Instead, look at the problem or trouble in a relationship as growth point to bond better. If this is done, pain is always a healer. Happy Suffering
