Hey there. It can be slow around here on the weekends, so please, don't get discouraged if it seems like people are just trickling in.
First off, please look in the upper left corner at the yellow box. Click on The Healing Library. Start reading. There's a lot of good information in there for you that has been written by people who have also walked this horrible path. Knowledge is power. In that vein, have you been to see a lawyer yet to find out what your rights are and about child/spousal support? You need to know all of this so that you can make good choices.
Please. Take care of yourself. Stay hydrated, eat what you can, and rest as much as you're able. You need to be kind to yourself and take care of yourself so that you can take care of your beautiful babies. From this point on, you sole concern should be your health and that of your babies. In The Healing Library, you will find a reference to the 180. Read it very carefully. This is meant for you, to help give you tools to detach so that you can start making decision based on what you need vice what you hope from him.
Come back often for support. We're all here for you.
