One more thing that scares me, im going on a 3 day bike trip starting thursday morning with my dad,brother and three buddiies, she said she would come back to the house to watch the dogs, im afraid I will come back to a empty house. And I know her GF will be here with her. should I hide my computer?my car? my clothes? or cant she do anything yet?
One thing needs amplifying here. If you decide to make the bonehead move of letting her stay in your residence while you go on the ride, then damn sure take precautions to keep things from disappearing or being pried into.
Ask your lawyer about bank accounts, retirement accounts and statements from them, about credit cards, assets like cars, etc. and tell him/her you're leaving for the weekend with the ex and her GF staying in the house while you're gone. Follow your lawyer's advice on how best to protect yourself from getting hosed in those few days.
Inventory and photograph everything there before you go. If the computer is your personal computer, then it goes to your brother's. Make absolutely certain that IF she can access your computer, you minimize the chances of her getting onto sites like this where you have posted about your relationship, finances or anything about the divorce. You don't want her even knowing what sites you go to. Erase the bookmark, history, passwords, etc. if she's going to have access to your computer. Even more important is anything you have in the way of notes or correspondence or any other stuff from your consultation with your lawyer, and any notes you may have at all about the divorce or settlement discussions. Keep it at your brother's house. If it's valuable and yours, do the same with that. If it's your personal asset or has your personal information on or in it, with any conceivable use to her -- at your brother's.
This is NOT the woman you dated or married!!! This IS someone looking out only for herself and her GF right now. And her GF hates your F*&%ing guts! Guaranteed! They're probably going to play house for the weekend and decide how they want to set it up as their nest once the male vermin is evicted. You're going to be even more welcome in GF's eyes (kinda like a giant roof rat with the plague) after their weekend in the house that you're keeping them out of with your selfishness.
You know not to get between a bear cub and the sow, don't you? Well, just figure that you're between two protective sows eager to cut your balls off and ask questions later, and in their eyes you're squatting in their den.
