she wont leave me aone

[00Ws6]

hey i need some advice badly i am currently 21 years old, but When i was 17 i was dating this girl and we only dated for 4 months but we lost our virginities to each other. We broke up and she has been in contact with me ever since we broke up. Every few weeks or month or so she will end up txting me or caling me, asking how i am if im dating anyone, she will tell me about how shes with something and stuff. About after a year after we broke up we ended up having sex again twice. She sometimes tells me she loves me, misses me and stuff but she says she only sees me as a friend. She will just txt me but she will never hang out with me except on rare occasions. Well this past weekend she ended up staying over at my house and we had sex 3 times, when we were having sex she kept telling me how she loved me and wanted to marry and have kids with me, how she couldnt find anyone like me and stuff. So she ends up txting me how she loves me for a few days, but then today i takled to her and told her i loved her and she was like dont tell me that were not dating. I have tried to tell her to stop taking to me and she will be like fine but then a couple weeks later or a month she will txt me again. i just dont understand why she wont leave me completely alone? weve been broke up for 3.5 years and we only dated for 4 montsh and she still txts me and cals me. I have asked people about it and they just tell me she probably still has feelings for me since i took her virginity but she doesnt want to be with me, she just wants to keep me in reach and stuff while she has fun. We have both dated and hooked up with other ppl since then but i just dont understand why she wont leave me alone? somedays she tells me she loves me/misses me and other days its i just see you as a friend and then she comes over sleeps with me tells me how she loves me and all this stuff and then it just goes back? i dont understand?
