I think it's a drive inside you because it's a control issue. The way I see it is that it is better that you don't know where she is. It would just drive you crazy. In some respects I'm glad that I live 1000 miles away from my wife. I can't do late-night drive-bys. I have no chance of running into her or seeing her out with someone else.
Just because you sleep at your father's house doesn't mean you have to live there. It also does not mean it is permanent. Keep a PMA about it.
Look, we all miss our spouses. Dwelling on it just magnifies the pain.
