I feel so bad for you...Like Sassy said your Mom obviously cares for you or she wouldn't make the phone call, and is scared if she gets caught talking to you for long she will be in trouble (due to her JW training). Maybe your boys can mail her a letter... can fill her in on everything and then they can say: Mom says...(fill in the blank...what you couldn't say when she calls you at work..) Just a thought....
Gee, I wish I had a MOM...lost mine to cancer when I was 14....But it must feel the same to have one and not be able to communicate. You must have been a teen when you were df'd. My kids don't know how I feel about the "truth" right now...and won't, cause I was too good of a JW mother when I raised them...Maybe one day, If I can keep trying I can help them with the "real truth".
Meanwhile, take care and know others here "feel" for your situation.
