Search Results: chance of getting back together

me and my boyfriend was just chillin at his place and we were cuddling and then we talked about our break up 3 weeks ago (he ended things with me coz he felt like he was the only one making efforts and more affectionate and that I always ignore his messages and calls and he had enough of it but I asked for a second chance and he gave me second chance and a week later, we got back together)
this was our conversation:
him - "did you talk to that guy that you used to be friends with after we broke up? he probably knows we broke up and u probably unblocked him and talked to him?"
me - "no i didn't.."
him - "tell me the truth.."
me - "i didn't unblock him.. but i was going to though. but i didnt"
him - "okay.. coz if u did, then that means he's your back up plan. and that you're just fuckin around"
me - "so what if i did tho? I mean i didn't but what if i did? we broke up..."
him - "we broke up for only a second.. if u unblocked him, that means you're not serious about getting back together... oh well.. if you do go talk to him again or any other guys (flirting), and if i find out, there's no second chance for that. i dont care. im going to move on. i have no time for that shit"
me - "soo you're just gonna move on just like that?"
him - "yepp. dont have time for bullshit. this happened to me with my first girlfriend. im not going through it again"
me - "if u move on quickly, means u never had feelings for me"
him - "no its not that.. i mean im not talking about now. im happy with you but if u do talk to other guys being flirty and shit, then im gonna leave. means i deserve better"
Does he not care about us?
Would he really move on quick? do guys move on that quickly?
