She made room for you In her one bedroom, she moved to a 2 bedroom with the plan you would both be there . In my opinion you are responsible for paying her at least 2-3 months rent so she can find someone to live with or find another one bedroom. If I was her I wouldn’t have moved from the one bedroom because she could afford that and if this one up and leaves she would be fine . But she moved to a larger apartment with you for you to just leave her high and dry. Nope, we’ll now she won’t trust the next person because of what you did. She helped you when you were in need and you just leave . Good job Judge Judy on seeing the right thing to do .
