caged bird syndrome 

When one is caught in the boring part of a relationship and they feel trapped and want to leave the relationship but they cant because they still have feelings for the other person. OR they are freaked out by how intense the relationship is when its only been a few weeks, so they want out but at the same time they dont.

She feels like she has caged bird syndrome because he told her he loved her after the 2nd week they were together.

Bird Cage Syndrome 

When one is accustom to residing in a confine space and suddenly finds themselves in a overwhelmingly larger space and in-turn becomes uncomfortable and hesitant to expand into their new found larger area.

Hey girl, did you hear that Magdalena is now living uptown? She was so used to living in that tiny 450 sq studio that she's now so freaked out about all this new found space and barely even leaves the bedroom. Wow she definitely has a case of the Bird Cage Syndrome.
