Should I reach out to my ex?

This guy that I had an almost relationship with (might as well have just been an official relationship) said he wanted to cut things off about two weeks ago because there was a pretty huge misunderstanding about the fact that I responded to a message on Tinder (we had never talked about being exclusive of anything) from someone he knew- none of it was flirty and I had no intention of ANYTHING as I really liked this guy.

Anyway, pretty much my fuck up. I didn't think me just TALKING to a guy would hurt him this badly as I thought he'd make us exclusive if he cared that much but I guess I was wrong. We talked twice on the phone after it happened for about an hour each time and he was so angry that he couldn't really reason with me at all.

I've been feeling extremely guilty for hurting him (not necessarily for the message, because there was nothing to it, and I wish he'd let me show him them because he'd se that too) because he's been scorned in the past by actual cheating. I wished him a happy birthday last Wednesday and he left me on read and the day before I had said that I needed some time to think and he told me that I should do what I need to but that he wasn't going to change his mind.

I really want to reach out in a week or two and just apologize one last time for hurting him because I'm just not that kind of person and he meant a lot to me so it's hurting me so much as well. I'd also like to hear what happened from his perspective and get some clarification.

**I was thinking about sending this: "Hi, I get that you probably don't want to talk to me but I was wondering if we could for a little because this has really been weighing on me, I've been debating doing this but I've had some time to think more clearly and I first of all still care about you and the fact that this hurt you a lot so I'd really like to be able to apologize again, and I'd also like some clarification on a few things beyond rehashing what we already talked about a few weeks ago"**

**Obviously I wish I could fix things but if he's not willing there's nothing I can do. Reaching out would really just be more for my own peace of mind so I can at least know I personally did everything I can do to rectify my mistake and prove how sorry I am. I know I'm risking no response but that in itself tells me that maybe he isn't someone I should be expending so much energy on.**

I haven't talked to him in a week and I'm not keen on seeming desperate or anything so this would be my last attempt. I know what kind of person I am and I would like to be the bigger person and at least know I was as kind as I could be so I don't have any regrets looking back.

Should I do it?
