Talked to my ex, did he say he’ll give me one more chance?

I talked a bit with my ex today I bit more than a month after he broke up with me. He admitted that whatever issues we had, it wasn’t just my fault, but his as well. I told him I’m trying to change (as I made a lot of mistakes) and that I want to and that I’m reading books, etc. He was a bit sceptical while talking to me, but the conversation ended with “we’ll see”. I asked what does he mean and he replied - we’ll see if you’ll change”. I’m wondering if that means he’ll give me a chance and I don't know what am I supposed to do next. How do I show him I’ve changed if he still doesn’t want to talk as much to me as we used to?
