I think this can be hurtful though...to them. The whole act of planning and performing a ceremony marrying yourself like this says (to me) I'm giving up. Not I love and am committing to myself. It doesn't seem like a healthy way to process the idea of being alone/single and happy about it to me. It comes off more like "nobody wanted me but I'll show them". But what do I know? Different strokes for different folks I guess.
