How [M]y ex-girl[F]riend from high school eventually cheated on her husband with me nearly 10 years later

This is a true story that basically spans an entire decade. Obviously all personal details have been changed.

I went to high school in a small town. My junior year a girl moved to the town from several states away; her name was Amy. As it turns out, Amy lived only about a mile from me, but neither of us knew that at the time.

Amy and I had several classes together, but I wasn’t attracted to her at all initially. She was quite tall for a girl (5’10” or so) and, while she was skinny, she was also sort of bulky, if that makes any sense. She just didn’t appear very feminine. She had this short hair cut that I didn’t find appealing. Her face was also not classically pretty. Her body seemed about average.

She started talking to me a lot and honestly I found her annoying. It didn’t occur to me that she was hitting on me until she became way more forward about it. At this point probably half a year had passed since I first met her. When I realized she liked me, I tried to avoid her even more, because I didn’t have the same feelings towards her. This is when I realized she lived so close to me, which I was pissed about because it meant she started asking if she could come over since I was practically within walking distance.
