<human>: This is around the two year "anniversary" of our breakup where I found out that my ex was talking to, and emotionally cheating on me over, the guy who cheated on her many years ago. This was known because I ran into one of her sort of-close friends (they don't talk anymore) who, after I asked out of curiosity, said the last she heard (a year ago) she was with him. I told her what she did to me and she was devastated, imploring I not worry about a shitty person like that and did add she thought (before we split) we would be the one for each other.

Stings, a lot.

Give me a shortened version of the text
<bot>: My ex of 2 years ago cheated on me then with, and is not together with, the guy who cheated on her many years ago.
