When should I talk to ex

So last night I fucked up when I was talking with my ex ( we broke up 2 weeks ago because we were having difficulties at the time but we got passed the issues ) and i want things to work out between us but I said something wrong and he got so angry at me but I didn’t mean it in the way I was saying and I still need to discuss my feelings for him and what I honestly think about everything but I don’t know when the right time would be to text and be like ‘ let’s take my dog down to the beach and talk ‘ like I’m thinking tomorrow i should ask him or give him space but it’s eating me up not being able to talk to him about everything and I had to go and fuck up the friendship we formed and I’m scared that he won’t even want to talk to me or meet up :(
