Srimad-Bhagavatam: Canto 8 - Chapter 1 - Verse 10
Sanskrit:
सालावृकाणां स्त्रीणां च स्वैरिणीनां सुरद्विष: ।सख्यान्याहुरनित्यानि नूत्नं नूत्नं विचिन्वताम् ॥ १० ॥
ITRANS:
sālāvṛkāṇāṁ strīṇāṁ casvairiṇīnāṁ sura-dviṣaḥsakhyāny āhur anityāninūtnaṁ nūtnaṁ vicinvatām
Translation:
O demons, as monkeys, jackals and dogs are unsteady in their sexual relationships and want newer and newer friends every day, women who live independently seek new friends daily. Friendship with such a woman is never permanent. This is the opinion of learned scholars.
