Try one last time or just give up? x-post

Throwaway here... It's been nearly two weeks since me and my-ex broke up for the second time. In our last convo (on google chat), he said some hurtful things, which made me angry and as a response, I emailed him and said some stuff now I regret, including saying I wouldn't contact him again... I deleted him from my contacts right after I sent the mail, but soon regretted that, so I added him again, but yesterday I found out that he blocked me on google chat (almost certain about that). I know that means he doesn't want to talk to me anymore (at least he thought that at the moment he blocked me). It wasn't exactly an amicable breakup, but honestly I didn't expect that he would block me... The thing is, the feeling of anger is now completely gone and instead I miss him a lot, I'm not sure I want to get back together again, but the idea of him being out of my life makes me very sad. I'm considering contacting him through email because I feel like I would regret not at least trying. Do you guys think I should give it a try or just leave him alone for good?
