I'm curious about the options of fellow moms

I told my husband that we were done 5 months ago. I have not been able to move out of the house, and he refuses to leave, therefore I have just been stuck with him. He refuses to accept that we are done. He harasses me about what I'm doing, who I'm hanging out with, and puts me down. Alot. We share a four year old daughter, and this whole situation is just toxic for her. And I, mentally, can no longer handle it. Is it terrible of me to leave for a couple of days out of the week, to get away from him, as well as trying to adjust my daughter to what it will be like once we are in separate households?
