Was i harassing her? Should i feel bad?

I live a 10 minute walk away from my ex girlfriend's area. There are a lot of places i like to go to that happen to be close to where she lives. She thinks i'm stalking her when i'm just minding my own business. I looked up from my iphone, sitting on a bench to see her standing right in front of me. She was being very rude to me, telling me that she talked to my mom again… I couldn't defend myself because she said "Don't follow me." Her mom came out of nowhere twice to bug me. Ex came out of nowhere again at night when I was just walking. She waited for me at the corner until I came close enough and made fun of me for having allergies. I was blowing my nose and she said "Ew that's disgusting" and kept insulting me. I snapped because I was already bottling the fact that she cheated on me with a perverted internet stranger, lied to *** me, and told me to die while I was crying on the ground. She insulted me then said "Don't follow me" but she was walking my direction anyway. I told her to leave me alone and be respectful. I should have ignored her but I was startled and provoked. When I'm already bottling Satan and the ex comes out of nowhere to throw insults at you, it's hatd to restrain yourself when she says "Don't follow me." Every time I ran into her before I said "Hi" and *** off immediately when she said "Go away." I feel like a criminal for telling her to leave me alone after she told me to not follow her.

No. Each of you are being rude, but not harassing. Try and avoid her, and when confronted, say nothing and walk away.
