I read your Newbie thread. I'm a newbie to the forum too. My WAS (also in PA)left 2 mos. ago. I wish I had found this forum right from the beginning. There is so much knowledge and experience here! I think it's great that you have the DB knowledge at the beginning of your separation.
I totally get your concerns on finances. My WAS lost a job and now I am the sole income. S is staying with family. One thing I did for myself to protect my interest and feel in control was open a second checking account. We have always had a joint account. I now have one third of my income going into this account that my WAS does not have access to. Everything else stays in the joint account (at least for now)so our marital obligations are still secure, WAS can buy gas for the car, food, dinner, etc. and doesn't feel cut off, but I have put myself first and feel really good about it.
When I first told WAS there was some strain but then my S said later on "Well, at the very least we will have a vacation fund when everything works out." Although my S was upset at first, I think showing my strength and resolve to take care of myself earned me a little respect too.
Hang in there!
