Im begging you guys for help w my ex ... he’s playing games ???

Okay so it was both our first relationship. I’m 18 he’s 20.

He broke up cuz he realized he didn’t want a relationship anymore and wanted to fuvk around. We only dated like a month. I had also only known him for ab a month. We moved too fast obviously. I think he was just desperate at the time.

Anyway we left on good terms.

He came in to my work (the gym) to workout and he stopped and was the one making convo for like 10 minutes basically saying he missed me and didn’t/ doesn’t know how to handle a breakup. He still has all the shit I gave him. Ik he doesn’t wanna get back together and I don’t either.

Anyway he came in again last night. He seemed like he was trying to act cool this time and like he didn’t care. But I was in the midst of a mental breakdown (I wasnt crying but just highly stressed and flustered) and so he half heartedly made like “why’re you stressed” type stuff but I was just not saying much. But it was embarrassing cuz again, flustered. So he’s like aight imma head out. Then he’s like you look adorable tonight btw. I said ... Uhh thanks and he just was like mhm.

So why is he trying to mess w my head and play games ?? We broke up a couple days before Xmas. I just want to stop having to deal w his shit. Also Ik he’s genuinely a nice person who means well , so this is what’s more confusing. He’s such a dick god. Can someone plz explain what they think. Ik I’ll try ignoring it now but I just need to know
