You have no responsibility to stay in a place that is not fit to habitate. Move. Today if possible. Let her worry about finding a roommate. If you can, give her the next month's share of rent to help her out but you aren't obligated to do this.
More importantly, how do you avoid moving all the bugs with you? They may have taken up residence in your clothing, boxes, anything. I would suggest you put as much as possible in garbage bags and leave them there as long as possible. Pick a suitcase of things to live in for a couple weeks and leave the rest to isolate. I would suggest looking on the web how to get rid of the bugs. Perhaps there is a site for 'how to avoid moving roaches with me' or something like that. I know with lice you need to leave them in plastic bags for 2 weeks but it probably depends on the life cycle of each insect. Good luck.
Move, just move and let this irresponsible girl deal with her own life.
