Move in with Grandma or Roommate?

My roommate and I have to move out of our apartment on July 10th. She found a house we could live in that would be under her name and I would have to pay her rent. I was also thinking about moving back in with my grandma to save money. Here are some pros and cons to both options:

Move with Roommate

Pros

1. Have my own space

2. I can leave the house without being questioned where I’m going all the time

3. Save an extra $200 a month

Cons

1. 35 minutes away from work

2. Spending extra money on gas

3. Utilities may cost more

Move back in with my Gma

Pros

1. 10 minutes from work

2. Save $1000 a month

3. I can stack my money until my long distance boyfriend and I are married (he’s 3 hours away)

Cons

1. My grandma and her foster kid can sometimes be annoying

2. Won’t have a place to myself

3. In the hood 😅

Out of all of these things, my main goal is to save money and I don’t want to move again until my bf and I are both ready to move.

PS: I can’t live on my own with the income I have and the location of where I am. I would find another job, but the company I work for is huge in my state and I get a lot of opportunities
