couple's coma

When people in a cozy relationship stop wanting to go out and just want to snuggle indoors. Sometimes associated with ignoring friends' messages or cancelling social engagements. Kind of like hibernation for people that are in love. Can get worse during winter.

Ugh, Ben and Alex are in such a couple's coma! It's impossible to get them to commit to anything and when they do come out they always leave before midnight!
