You must like living around stressful people. You aren't married to this person.....you are not compatible in your values.....stop trying to force a square peg into a round hole. You are wasting yoyr time while she is using you for a place to stay. Is that really what you want your life to be like?

If not you better start making better choices & realize that NOT every woman who shows interest in you is a possibility for becoming a GF. Get to know them first before making any committment to hsving them move in.....unwise choice on your part.
