i think about this girl i have known since i was 7 years old,she is the same age as me,we used to hang out with each other up till we were 13 years old then she moved away

she asked me out a couple of times (but i was so young at the time and everyone used to tease me and her for always hanging out with each other)so i said"i'll think about it" i was an idiot!
so she moves away and im missing her for like 6 weeks then my dadstells me we are going to there place for the weekend

so after 2 weeks of not seeing each other it was kind of weird she had new friends and stuff now but we hung out the weekend and she's flirting and all then the weekend is over. i never saw her again.
so when i was 16 i thought i'll give her a ring and we started talking and all and she said that she realy miisses me.she told me she just broke up with her boyfriend

and she sais she wants to meet me etc etc.... but she lives 150 miles away and i didnt have a car.so i ring her up a week later andthis dude picks up the phone(i had a funny feeling in my head that that was her x)so i asked her who that was and she said she was back with him,cool i said i'll ring you back later so we can talk she said "o.k" i never rang back because of her getting back with him and i didn't want him and her to have an arguement etc etc etc ... so i left it as that.
but im 21 now,and i still think about her every day.what should i do?
how do you think she would react to hearing from me again ?
i realy miss her .plz help me.
