How do you differentiate between "They drifted away because they realized they weren't going to get it," and "They drifted away because your relationship was so engrossing you lack any desire or motivation to include them even as friends, thus pushing them away."

These two situations are very similar looking from the couple's perspective.

"They're always doing couple shit..." 

Yep. Who are you to judge?
