ex lovers

so before me and my boyfriend started dating, he was with this girl for 2 years and they only ended things a little more than 6 months ago. he’s told me before that she was his first love. he told me yesterday that they still talk and he didn’t want me to see her name on his phone and freak out because he is happy with me. do you think it’s possible for a guy to be friends with a girl he was in love with?
