Trust in a relationship is so important. I was in a relationship a few years back with someone who I could not trust as far as I could throw him and it was hell. I was constantly paranoid and checking up on him. Eventually I ended it and it was the best thing I ever did. Like someone else said, life is too short and I don't think you can ever be truly happy without trust. My partner now I trust with all my heart and I know he will never intentionally let me down or hurt me xx
