Our Gemara on Amud Beis discusses the situation of a man marrying a woman and then discovering that she had many oaths which has an impact on their personal life. This may invalidate the marriage, as he can say, 

‎אי אפשי באשה נדרנית

I did not want to marry a woman who is a serial oath maker.

Aside from the basic burden of being liable for too many restrictions, Maor Vashemesh (Matos 8) suggests a more characterological problem. He says that excessive oaths come from anger and arrogance. He also sees it as coming from poor chinuch where the parents did not set appropriate boundaries. He derives this from the verses themselves, as it states (Bamidbar 30:5): 

וְשָׁמַ֨ע אָבִ֜יהָ אֶת־נִדְרָ֗הּ וֶֽאֱסָרָהּ֙ אֲשֶׁ֣ר אָֽסְרָ֣ה עַל־נַפְשָׁ֔הּ וְהֶחֱרִ֥ישׁ לָ֖הּ אָבִ֑יהָ וְקָ֙מוּ֙ כׇּל־נְדָרֶ֔יהָ וְכׇל־אִסָּ֛ר אֲשֶׁר־אָסְרָ֥ה עַל־נַפְשָׁ֖הּ יָקֽוּם׃

…and her father learns of her vow or her self-imposed obligation and offers no objection, all her vows shall stand and every self-imposed obligation shall stand.

Maor Vashemesh asks, why does it say “all of her vows”? The answer is, it implies a pattern of making vows. The verse is also hinting at the father’s silence in not objecting, that is not providing her with proper guidance and discipline
