This isn't really my experience, although, I'm not generally friends with very flighty people in terms of relationships. I do know some, particularly iEEs, that are more as above.

Many of these NFs seem more intrigued with the pursuit of relationships than they are with actually being in them - even ENFps need to occasionally step away for objective assessments. The most common phrase that I've heard when NFs become disillusioned with relationships is some version of "I don't have the time or energy for this"; however, they start to subconsciously detach themselves long before mouthing such words. Delta STs seem to be good at sensing the subtleties of detachment and will either attempt repairs or look for other relationships; the STs seem to be the first to lose trust while their partners lose interest. The success of the dual relationships seem to revolve around continual adaptations by the Delta STs to provide fresh illusions of Edens.

a.k.a. I/O
I can most confirm that when delta NFS seriously start voicing concerns about things it's because they've exhausted whatever their allotment of caring about things has been. Delta NF relational fights are generally about trying to get someone to 'wake up' and show interest in them how they want to or learn things that they need to change to still pursue that potential or their vision of things, rather than anything else. At least the ones I know that have been significantly vested in relationships. Hope is a primary currency for them.
