I’m a looong time BT & my husband is a looong time CT.
I was in the core start-up group of M.A.S.K. & the one thing that troubled me the most in parents’ discussions was how many supported the ‘tough love’ approach. throwing the child out of the house?!
keeping up communication*,and giving un-conditional love & support … B’H, it worked for us! (*heavy-handed, repetitive, guilt-inducing, mussar-giving by one of us didn’t work, & still doesn’t). respect is also key.
Chasdei Hashem, the children (all FFBs) ‘cleaned up their acts’ & have gone on to Torahdik marriages.
my older daughter, whom I respectfully & affectionally call ‘the Rebbitzen’, was never affected in the least– insofar as her beliefs. of course, she was veryy concerned for her siblings, but implimented love & communication & respect as well. she is a role model to all of us.
