<human>: Trying to sort out my feelings for a gay couple that I met awhile ago but have become very good friends. I've always wanted a threesome with them, but have always been told that while they consider me a very good friend, they're simply not interested, that and that they're monogamous.

Fast forward a few months and I'm hanging out with one of our mutual friends and just shooting the breeze when the topic of this couple comes up and he casually mentions that they had a threesome awhile ago (this guy is 32m). For some reason (even though the idea of a threesome with them had come up a year or so ago and had not been brought up since), the idea of this really cut me – even though I had no reason to feel slighted - and I'm struggling with a sense of jealousy that I really have no entitlement to.

As a note, they're really nice people and have in no way been misleading me, this is really my own issue and I'm trying to sort out why I have such feelings for them. I know they care for me deeply and I don't want to hurt them in anyway – which is why I have to sort this out myself.

Can you give me a shortened version of the text?
