My boyfriend has this necklace that means the world to him and he gave it to me before he went to Arizona. I've had it for a year and I lost it recently. I thought I was safe because he never said anything about it. Tonight, he asked me about it. I lied and said it should be upstairs. If he knew, he would be so upset and I don't want to lose him. My mom won't let me buy a replacement necklace, and I don't know what to do.
