I've had the same ten friends since college. It's has a mix of genders and multiple people have dated each other.

For me, I dated "Matt" for a year, but it fizzled out when he wanted free time and I was career-oriented. We agreed to remain friends as we would inevitably meet at our mutuals' hangouts. We didn't want to make it awkward.

Other ex-couples have done the same, and everyone said it wasn't a big deal. However, the awkwardness never vanished, and I avoided one-to-one conversations with Matt.

Fast-forward three years, and Matt is marrying another girl, "Emma" in our clique. She is a lovely and I wish them a happy marriage. However, they want to invite me, and I feel this is getting bizarre. Besides online stories, I have never heard of Exs being invited to weddings.

I have no romantic feelings towards Matt, but can I pretend our history never happened? To be blunt, it feels wrong at a wedding when you've been intimate with the groom.

I texted Matt and Emma that I'd send them a wedding gift, but I would like to withdraw from the event. They accused me of being jealous and not putting my feelings aside for one day to support them. They want everyone to be unified.

I assured them: "I don't have any feelings towards Matt. It is simply awkward. I know it's normal for exes to remain friends in our group, but it's pretty uncommon thing, and you can't expect everyone to handle it the same way."
