Primarily, I don't want to provoke my W into retaliating and changing the locks on our house. That's just not a battle I want to fight right at the moment.
Second, I gave W a key to my apartment in the beginning under the notion that we were going to work on our R/M; and that I wanted W to be able to access our S's in our place in case or an emergency. I was just thinking of this as a mere precaution.
Lastly, W wanted to be able to come over during the summer while I was at work to allow the children to swim in the pool here.
But then, it has been almost seven months now. And if W does file for D, I will definitely expect her to give me her key back -- in fact, I will insist. In the mean time, however, if she continues to abuse this courtesy, I will have to take action sooner.
