Does it normally take 8 years to get over yohr first breakup?

This site tells you not to ask if its normal that someone broke your heart; however, I am wondering if it is normal to feel the effects of it 7\8 (I don't remember exactly) years later.
I was in middle school,12-13 or so years old, and it was the first relationship I'd ever been in; I'm very fuzzy on the details. I do not remember how long it lasted, or how we met. I remember the guy's name but not much more then that, if I see him again or a picture of him from when it happened I doubt I'd recognize him. I know he was older than me, but do not know by how much. I remember hardly any of what we did, but I do know that we were very affectionate. I also know that I got into a lot of trouble at school for doing things like hugging or holding hands with him, that I had few friends at the time and that I and the school staff were always at odds. I can remember that we saw ourselves as sort if rebels who only had each other; I remember how it ended.
I cannot pinpoint the date or the year, but it must have been winter because I remember snow. I do not know under what circumstance, but he tried to kiss me on the lips. I pushed him away and ran for the school building, and a teacher saw it. I remember crying and sitting for hours at the office, but not what actually happened during that time.
My parents blamed the incident entirely on me and I was bullied over it for the rest of that year. Then I moved schools and saw none of the same people again.
Ever since then, I did not feel an attraction to people of any sex and find it very hard to talk to men. Even though many have confessed their feelings for me in these eight years, I have rejected all of them, and rather rudely. Several I reported for sexual harassment, just as a precaution, and always carry a rape alarm. I have never displayed any affection towards a man, and though I have hugged and touched my female friends and been to sleepovers with them, I would never sleep in the same room with a man, even a family member. Though I must admit I sometimes enjoy reading erotica, the thought of myself intimate with someone makes me sick because I would never be able to trust them.
This being my first time speaking out about this, it was not easy to write. I am wondering if feeling this way so many years later is normal, and if anything needs to be done about it.
