Yes.. absolutely protect yourself ! I dont know how YOU will do it.. but for me (my w is Bipolar and we are sep. soon to be D) I insisted that she spend $$ out of her own account.. we have 3 kids too.. so that really complicates the finances.
Protect your credit record/score etc..
I dont know if that helps.. but god these MLC'ers and mentally ill spouses can kill us financially... nip it at the bud !
oh.. and OM is named Bruce.. so If I get cranky with you.. um dont hold it against me okay ? You dont drive a BMW Z I hope !
