Should I get a job at the business that my girlfriend works for?
Why are you going to work at the same business your girlfriend works?
I love her and want to spend as much time as possible with her.
I know you want to spend as much time with your girlfriend as you can, but remember that she needs her space. Your relationship may suffer because you two will be together all of the time. Talk to your girlfriend first and see how she feel about this.
I'm going to take this to a manager.
You need to speak to your girlfriend first, this could do the opposite of what you want and drive her away.
