Trying to figure out a plan

I spent this morning exploring my options as far as where would I go if I left. I started looking at apartments in the area.
How the hell does anyone afford this shit? I took a part time work at home job so I could be with my daughter more often but I have no idea how I would ever afford living on my own. If I decide to leave I will figure it out even if it means a roommate or something but seriously? How can I afford this?
I told him last night that we need to separate for a couple of weeks so I can figure things out now that the original shock has worn off. I'm terrified of being alone but I think it will be for the best for me to have that time. Tonight we will discuss logistics of all of it and he will leave.
Tonight is also our 2nd counseling meeting.
