Why is she copying me and how do I get her to stop?!?

Well, one of my friends that I've known since high school seems to be trying to copy everything I do lately. She never was like this before. She and I used to have vastly different styles, personalities, and views on things, and had different dreams. But now it's like she's trying to do everything like me! O.O It started when she decided that she didn't want to go into the medical field anymore and decided she wanted to run her own bakery. She knew that it was always my dream to do that, but at the time I didn't think much of it and thought it was pretty cool. I told her that I've been selling the things I've made around offices and such, and she started doing the same thing. Then, she started dressing a little more like me and has been wearing more dresses (even though she hated them before) and she's been trying to do her makeup and eyeliner like me (she also used to not like wearing makeup). Again, I didn't think much of it.Then she started acting more girlie and talking in the same manner I do. And recently, I told her if I happen to not run a bakery, that I wanted to try and become a florist since I really love flowers and making arrangements from time to time... And now she's finding work as a florist! I am starting to find this a little weird...She's acting nothing like she used to... I don't know if I'm looking too much into it, but I think it's just a bit too coincidental. What would be the best way to deal with this?
