DEAR ABBY: My sister recently got engaged. I’m ecstatic for her. Her fiance is amazing. We have always been close, and I’m going to be her maid of honor. The problem is, since they’ve been dating, and especially now that they’re getting married, I’ve been jealous. I feel like a little green monster when I see them together.

It feels like a punch in the gut when they’re being couple-y and I’m third-wheeling. I hate fighting these feelings when I’m truly happy for them both. But I feel jealous and then guilty for feeling this way and I’m sick of it tainting my genuine happiness.
