I want to take my girlfriend somewhere to show her I love her and that I changed cause I use to be a to her but I changed and I want to show her that I love her where can I take her

If she really likes you, it won't matter; but not a movie. How about a good hamburger and game room where you can play billiards. BTW, my cat shares your name; I had to get him fixed, and he still gets into fights.

So you've done some growing up and would like to try again with this girl? There is only one way for a grown up to show someone that they are interested and that is to put a smile on your face and go up to her and say, "Hi!"

Is she giving you another chance, as your post is unclear. Also your ages, and how long have you been together, would help.

Don't "take her somewhere"... be there for her.

We're going to need some more info here...
