from now on document all financial dealings between the two of you, even before the case goes to court. insist on bank transfers and if there is any cash payment (like school for kids, food and so on) get a recibo. this may be useful in the future. do not delete any voice mails, whatsap messages or texts from her. keep your calm and stay classy no matter what she does or says.
and most importantly. stay positive.
