<prompt> Human: Hey guys, Im in a new situation here and I just want to make sure Im properly helping out money-wise, but I dont want to be taken advantage of. Im always that guy that ends up paying more money when dinner bills are split just because..Anyway, I moved in with my girlfriend. She owns the house we live in outright and has for a few years. She also has a 3 year old son living with her. Since Ive just moved here, I dont currently have a job but that doesnt mean I dont want to contribute what I deservedly should. I presently watch her son M-F all day while shes at work.Shes told me well, Im not going to ask you to pay for utilities since you dont have a job right now.. but Im still going to. My question is how to split the utilities with her. Should it be split three ways because there are three humans in this house? Should it be split two since there are only two adults? She has satellite television which I never use unless its watching a childrens program with her son. Should I be contributing with that?I buy my own groceries cheap things like pasta and oatmeal since money is tight for me right now, but she often makes dinners for all of us using what shes purchased. She has mentioned she wouldnt mind if I helped pay part of the grocery bill. She exclusively shops at Whole Foods which is ridiculous. For what she buys, I could buy it at a regular store for less than 13rd of what she pays. What am I supposed to say? Well you spent 150 on groceries, but I could have purchased it all for 40 so ill give you 15 since I hardly even eat the food you purchase? I dont want to insult her. Any suggestions you can send my way is appreciated. Just new to this kind of stuff.  <response>: You three are now a family. Split stuff down the middle between the two adults that are capable of finding gainful employment.
