Is my feeling wrong for this girl ?

My senior year in high school, I met this girl and we became GF and BF . She always wanted to talk to me, she was kinda clingy when we was together .We broke up after high school . Even though we was together for like 10 months we never when on a Date .

After we broke up, she stop talking to me for like 3 months . Then one day she text me and we start back talking . Since I had my brother car and job I decided to take her on a date before she go to the Navy . I spend a lot of money on the date, trying make up for not carrying her out in those ten mouths .

After the date, she went back to her old self she wanted to talk to me all the time . When I told her my brother took the car back, she stop talking to me and every time we talk she kept ask me if i had the car . Today I told her i got the car back and now she talking to me a lot.

Right now, I can't stand her cause I know she want me to take her out. I think it's mess up she only want to talk me cause of the car. So am I wrong ?
