Why did my ex boyfriend send a check up on you text after a month since we stopped talking?

My ex boyfriend and I broke up on may because I couldn't communicate with him and started losing feelings for him but we kept in touch with each other but then we stopped talking for 3 weeks after an argument and I reached out first and we started having meals together

One day when I was looking through his phone I found messages from a former friend group talking bad about me calling me a pick me girl and a crazy b*tch and I lashed out at him and telling him that I want to hit him and I told him to leave me alone and I want nothing to do with him but I didn't block him and after a month he texted me, checking up on me and even sent me a funny video to cheer me up, should I reply to him?

Update: He didn't talk about about me, he was only present in that friend group but didn't say anything, that friend group was only spreading rumours and calling me names to dissuade him from getting back with me
