TGIShabbos,
“Many shidduch offerings were not ‘religious enough’ for them, but were somehow suitable for other FFB yeshivish guys who became engaged. Disposing ALL of their colored dress shirts (I didn’t need to go shopping those years). Not wanting to EVER return back to their non-religious home, although they said their parents were respectful and accommodating- “
It’s possible that these behaviors were expressions of religious fervor, but more likely they came from a place of immaturity. Turning down shidduchim could indicate a fear of commitment, for example, and the rejection of their parents despite accommodation could have simply been teenage rebelliousness. Building a healthy frum lifestyle requires a solid foundation: faith in Hashem and recognition of the Torah as truth, a clear plan for spiritual and religious growth, and a rabbi as a mentor and posek.
