Yes, it is quite true that any relationship of love and friendship will not work only on the basis of trust from one side. It is believed that any relationship is a bond of trust or faith. It is totally based on the bridge of trust. So, due to lackness of trust from one side, it is quite fair that the relationship will fall under one side to work. Relationships are the relations of two people and also maintaining trust is responsibility of both.
It is quite unreal because how can a relationship stand if there is trust from one side. Trust has always been on the top of the priorities when it comes to the main ingredients for a successful relationship to work. People should be practical about the trust part because dating a person who does not trust you is equal to waiting for the 30th Feb, it is obviously unreal and unreasonable to not trust your partner when you commit that you are totally in love with that person.
