How can I win his heart back?SOMEONE PLEASE ANSWER!!

Hey guys I have a question! Me and my ex broke up like 2 months ago. We still talk and stuff and we argue, like we’re still together. He says he loves me one day then says he doesn’t love me the next.He never denies my love for him though. I’ve done somethings that seriously has hurt him like lied and stuff and he still seemed bitter towards me. so I stop talking to him for about a week to let him I guess calm down and I texted him yesterday to see how he was and he said he was aight in capital letters. Then I told him that I was just texting him to say that I loved him and that I missed him and stuff and he said ok thats cool, when usually he’ll like cuss me out or something. Then I told him goodnite and he said bye and I told him to be careful and he said always.Tonight I sent him a text saying that I loved him and that I wanted to be with him and I told him to think about it and then I said goodnite and he didn’t respond yet. How can I possibly win his heart again and since he isn’t responding to me in a negative manner anymore, does that mean he may be coming around??? we’ve been through a lot and we’ve known eachother since we were like 5.
