I told my ex to make a decision on either being with me or letting me go?

We broke up and I said I still wanted to try and work things out cause the break up wasn't thought through and he said he doesn't know and I gave him a couple days and I told him today I want his answer but he wasn't available all day and came back tonight and were just having a normal conversation like everything is fine but we are exes, thoughts on what to do? I need to know where I stand , he calls me baby now and then , gives mixed signals but doesn't say anything else.
