OK question for the divorced women?

[survivor]

i saw my ex in walmart today. i don't have any kids by her. she had one by another man and i have 2. i was in line and looked up and didn't recognize her because i haven't seen her in like a year. divorce was ugly. i stay away from her because of it and haven't contacted her at all. i saw her and stayed away. she made a point of walking right by me within 10 feet when i was in line. what's up with that? plus she was a brunette...both my kids were blonde. she was always upset that she thought i liked blondes.....low and behold when she walked by....she is now a blonde. i only recognized her by her walk. i stayed away but she made it a point to walk right by me. I didn't say a word. in my eyes, it's over she's just another girl but if i saw her i'd make it a point to avoid her. so what's her issue and she always hated my reference to anything blonde including my kids...now she's blonde. in girl speak what does this all mean? i mean the woman made it a point to walk right in front of me.
oh and by the way she always played the victim and said i was dangerous so i made it a real point to stay away. yet she saw me and came from the other end of the store and walked right in front of me. i'm dangerous eh?
