What should I do?

Since the  last time I wrote, a lot of things happened..
On the day of the last post she invited me back and since then I'm here with them.. But not for long..
The little girl's father is coming back a week from now and I have a bad feeling about it..

Even now it feels like everything is going wrong, like I'm just some kind of a plan B..

I don't know what to do right now..
How to handle things in a situation like this..

Can't find the words, don't know what to say..
I'll write again today..
