CAN I DO IT ?

ok so I made the mistake of saying my dad was moving out and I was scared I wouldn’t be able to keep up the bills and stuff of the house by myself around this girl and now she wants to be my roommate:( and she is getting so excited wanting to move in but I really don’t want her to.

so I have two questions

1. do you think I can manage the house by myself? I make 1600 a month. sometimes with with overtime. the house payment is 617.00 and my car payment is 254.00 but you also have to factor in power,water, gas, sewer, WiFi and groceries and something else I am probably forgetting. I need someone who is good at budgeting to tell me if it is possible for me to do this because my father is only paying the bills down to zero this month then it’s my turn to start.

2. If I CAN do it then I don’t want her to move in so how do I tell her I don’t want a roommate
