Financial talk

Hello! I am a nanny and I just got a new its a live in position but I have a place in another town 30 min away from here...I am only going to be able to spend the weekends at my place which I pay rent for I was making numbers and I dont think its worth it to keep paying rent for my place,..when I got hired the family was offering certain amount of money but I asked them a little bit because I needed it to pay my rent and now that I been thinking about no live there anymore I am afraid if they want to lower my salary to the original amount... What do you think?
