Why did he feel like he needed to tell me?

This is about my ex of 3 years who went to prison, and got out June 2021. I have old posts on here talking about him. However long story short, he is an addict/narcissist and threw me away like garbage last April and has had a girlfriend since August. However he hit me up a few days ago out of the blue. He told me him and his girlfriend broke up and he OD. He told me he tried to kill himselt and i asked why he is even contacting me and he said “I thought I needed to tell you”. Why would he need to tell me that he almost killed himself? We are still talking but i have mixed feelings about him. He is going to detox tomorrow. He admitted to me that he has been using since he got out of prison.. great. And he still gaslights me and denies certain things.
