Where do you draw the line with a partners ex?

This is for you guys and girls, where do you draw the line and say something about your partners ex?

My boyfriend was speaking to her months after the relationship ended, she was in a new relationship but kept him their for emotional support. She was suffering from mental health issues and self harmed so I understood why. Also they were long distance, and he showed me all the conversations, which were mostly just chit chat.

Until they weren't... one day she messaged a lengthy text saying she still had feelings for him and thought about him every day. I was very upset as she knew he was with me. He told her he was happy with me (short version) and that was that.

About a month later she sent him a picture of a love letter she wrote to him several years ago, it actually said 'I love you 'name'.
I said that it was very inappropriate so he asked her why she sent it, she said well I can hardly send it to my boyfriend and it was for nostalgia. I said that's bull, she still has feelings and asked that he cut contact.
I feel the line is crossed when an ex expresses that they still have those feelings, then it's no longer friendly conversation.
