<human>: Condense the text into a few key points

My fiancee (21F) broke up with me (23M) in Sept. to be with another guy. They were sleeping together while i was still in the house in the process of moving out. She put me through a lot of shit, but it's hard to forget 5 years.

To get over her i blocked her on everything, yet she still found ways to contact me for stupid reasons. She is using other people to get close to me and it is sickening. She befriended a friend of mine to use his Facebook to find out about my new girlfriend.

Recently this halloween, she got herself in jail and called me to bail her out (did not answer) and made her mom call me as well (not answered as well). She lost her jobs and dropped some of her classes. After cheating on me a few times, i shouldn't care about her and should laugh at her downward spiral, but i can't.

It's been a month now since the last contact and i'm preparing for another encounter soon (especially this holiday time when she has no one). Normally in the past i just never answered or deleted messages. Should i have that one final talk with her? I need to completely forget her but i don't know what to say or how to act. I know a lot of people go through this and i appreciate any help.
<bot>: My ex broke my heart but kept contacting me. It's been a month since she contacted me last. What should i do if it happens again? Talk to her and tell her to stop or ignore?
