<human>: Me and my ex broke up a week ago and he wanted to "never speak to me again". We dated for several months. The relationship was great when we were together! The relationship had just become long distance a month before, and the problems came from that. I've never been in an LDR before, he has a couple times. 

Problems on my part - jealousy, feeling the need to be controlling. I realized this is because I was so far away and felt afraid and helpless. I'm also quite high maintenance - I like a lot of attention. I get angry quite easily too. I agree with the problems and I need to address them. I've really realized that I screwed up. I think I was afraid to tell him that the distance made me insecure as well.

I thought it was over, because he made it pretty clear. I was going no contact because that's what he wanted, but I messaged him to check he was ok after he posted a sad face on snapchat. We briefly messaged about us. The summary is, he misses me but feels super hurt by the fight we had just prior to the breakup, and my actions leading up to it. He isn't ready to talk it through yet but he said that he loves me and is willing to wait for as long as it takes me to change.

So. I've done a lot of thinking about it. I also changed some medication which has dramatically improved my mood (no more ups and downs, which is amazing, I should have seen the doc before). But I'm not sure how I can show him that I'm working on myself if he won't talk to me? But I don't want to contact him until he is ready. Any advice?

Thanks!!

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Ex wants to see changes in me. How can I show him if we are taking time and space away from each other?
