My bf and his ex broke up around 2020-2021 but were off and off for a little bit. We have been together 1 year, he has been off with her for about a year before that. She’s an alcoholic and was abusive (police reports) and he’s in therapy.

She was reported missing and a family member reached out to see if he had heard from her (as this used to be the cycle). The story he tells me is he got angry and unblocked her and told her to tell her family to leave him alone and stop contacting him about her. He then deleted these conversations. I found out because I noticed her name disappear/reappear on some Facebook posts and I asked him if he had been talking to her. I also saw her posted as a missing person so that is true. I asked to see the messages and he told me he deleted them, he felt guilty for texting her and wanted her gone from his life. He didn’t tell me because he didn’t want to upset me. I’m worried that he’s hiding things from me now, or that he’s not really over her. Is it suspicious that he deleted everything?

TLdr; bf secretly reached out to ex in anger when he was contacted by her family after she disappeared in a relapse, deleted messages. I’m worried there’s something more he’s not telling me or that he’s not really over her. How do I approach this?
