Break up - still friends

We have been together 4 years, I slept at his Sunday - Thursday Friday I collected him and we were on our way home and we spoke on going ice skating Saturday (today) but I mentioned after how he needs to stop doing xyz (something disrespectful or else I’d lose feelings) he said okay was jsut dropping him home he asked to talk for a minute (over an hr) and we ended up talking about our relationship and then he said he feels numb and that he doesn’t cry over me anymore, which he then started crying when he said he thinks it’s best we leave it. He then mentioned how he loves me he’s trying to become better etc etc… we still talk … he said he had this planned but yet he was so normal the 4 nights I stayed over and hugs kisses.. and then we made plans for the Saturday but he broke up with me the Friday? How does this work what do I do ? I’m thinking maybe like texting and being “friends” won’t work and if I jsut cut most of the contact for now to get over him he’ll miss me more
