People are always talking about wanting to move to whatever city or state. Until she has SOLID plans to do so, you should not worry. When I say SOLID plans, I mean like she has the money to move along with a place and a job to go to.
People dream of going to New york, Cali, Florida, etc but then reality speaks up with, "Oh yeah, and how do you plan on financing this move? How you gonna pay the rent? What happens if you run into problems...?"
Kind of like when we were little kids and would "run away" with our favorite toy and an entire day's supply of PB&J sandwiches. Oh and one change of outfit. Yeah when I was 7 years old I did that but none of the empty apartments were unlocked and it was cold out.
I have an older sister who keeps talking about moving to Florida but it has been nothing but TALK for about three years.
So, even if she DOES decide to move in 6 months, by then a lot of your infatuation should be settled and it won't hurt as bad when she moves out there only to find no job, run out of money, and has to have her parents send her gas or bus money so she can get home.
While we are on the subject, how do YOU plan on financing a move out west?
Always remember that YOU are the most important person in your world.
