I suspect your reluctance stems from your feelings of shame that such a step is necessary. But don't look at it that way; look at it as yet another opportunity to provide for your kids. A means to the end of preserving their home.
I suspect you don't know me so don't dare to assume you think it's due to shame Ellie. In fact, I'm finding a lot of your post to be condescending so knock it off. You've made quite a few judgments about me and my actions and while I've tried to come off as understanding you're starting to irritate me.
I have a 12 year old daughter and a 17 year old daughter. I don't want anything bad to happen to them and since my W was raped by the neighbor kid when she was 12 I think I have a valid concern for my girls, don't you?
There will be no strangers living in my house as long as my daughters are with me. Got it? It's not shame, it PROTECTION.
And no, I'm not in my 'deep depression' any more. Nor am I being 'passive aggressive'. I'm being to the point and assertive.
I take responsibility for my actions, and the safety of my daughters.
