[good times]

I guess my take on this is totally different from the others here. From what you have said here it sounds like you are way more emotionally attached to this couple than is acceptable or comfortable. The reason I say this is that this story sounds like several experiences we have had where we were the other couple in this story trying to extract ourselves from someone who has become too clingy.

The bottom line is, I think you are taking this entirely to personally. My guess is that the other couple is trying to ditch you while at the same time trying not to hurt your feelings. And yes, what they have said to you probably is total bs, but then, I can tell you from experience, that were I in their situation, I would do the same. We have tried the honest approach when dumping someone that has gotten to attached, they get more pissed than you are now by several orders of magnitude. So, this is the one time when I would advise against the "honest" approach, the drama just isn't worth it, I would have most likely done the exact same thing the other couple did.
