Should I be mad my boyfriend lied to me about emailing his ex?

The circumstances are terrible so I feel as though I can’t be mad even though I am. My boyfriend father passed away. The last email he got from his ex was petty and was her trying to stir up drama and was random. So I asked him not to speak to her again or the next time she reached out tell her not to anymore. But hearing about his dad she emailed him about how sorry she is and he’s in her thoughts and to reach out if he needed anything. They email back n forth about 2/3 times on that thread about how his feelings and her offered support. . I asked him days later if he has heard from his ex bc her family had been reaching out to him. I asked 3 times and he lied each time. after the third time he admitted it. I feel so conflicted. Am I wrong for being upset am I being insensitive. I’m trying to move past it but I feel like it’s causing me anxiety and hostility. I don’t know how to move forward from here
