...I'll try again.

I would invite Jamie to bring her butt, and Suzy back "home".
Get Suzy back into the state you live in.

Give her her (Jamie) freedom (as long as Suzy is safe with you and Mike),
to make choices,
...good or bad.

Give her the proverbial "rope to hang herself". If she does right
by Suzy and you and Mike, all is well.

If not, then take her to court for custody. I had to but Bug's legal
fees on a credit cardimage

Once you have custody, you can let go and let God be with Jamie.

Set your bounderies as far as her contact with Suzy, and she wouldn't
be allowed to sponge off you and Mike if it were me (and it's not).

It's kind of like tricking her to believe that SHE is the center of your
attention. That you want HER to have the loving home you can provide
for her and Suzy. In the end your main concern is for Suzy at this time.

I told my daughter "If you're going to use, please, please, be sure that
you leave Bug with me. She bit that one hook line and sinker and ran
off right before Christmas last year and didn't return until Febuary. That
was enough time for me to claim she had abonded Bug (which she did),
and gain custody of Bug.

Give her permission to go back to CA if she wants, as long as she leaves
Suzy with you. She knows you and Mike are the best for Suzy at this time.

My prayers are with you.

Keep On Truckin'
