'Unbeständig' (changeable / fickle / unstable) consists of the prefix 'un-' and the adjective 'beständig' (constant / stable). Here, the prefix negates the quality expressed by the base word.
Wegen des unbeständigen Wetters planen wir lieber keine lange Wanderung.
Because of the changeable weather, we'd rather not plan a long hike.
'Unbeständig' (changeable) is particularly common with 'Wetter' (weather) and 'Witterung' (weather conditions). The phrases 'unbeständig bleiben' (to remain changeable) and 'unbeständig werden' (to become changeable) are also typical in weather reports.
Am Wochenende wird das Wetter wieder unbeständig.
The weather will become changeable again over the weekend.
Use 'in' with the dative to specify the area in which a person is 'unbeständig' (fickle), for example 'in ihren Gefühlen' (in her feelings) or 'in ihren Entscheidungen' (in her decisions). When applied to people, the adjective usually conveys a negative judgment.
Sie ist in ihren Entscheidungen so unbeständig, dass gemeinsame Pläne schwierig sind.
She is so fickle in her decisions that making plans together is difficult.
In technical and chemical descriptions, 'gegen' with the accusative identifies an influence that a substance cannot withstand. 'Bei' with the dative, on the other hand, specifies the conditions under which the substance is 'unbeständig' (unstable).
