I need an instruction manual

I am a July Leo, dating a Pisces. Recently he's told me he doesn't want to date anymore. He said he was tired of my attitude when I get upset with him. I got upset because we made plans and he made other plans on top of ours and didnt tell me until 30 min before when I contacted him and hes was already in route. He wanted to go to a party. Thats fine. But why not say that? And why get mad at me when I get upset over your actions? I wasmt hateful. Just short and a little smarty. Now I'm so regretting it. Ive tried groveling and apologizing saying I could of reacted differently. He says he wants to be friends still. I told him I cant be friends right now and asked him if he cared at all or at any point to block me. He hasnt read the messages yet. Did I mess up?? I dont know what to do. Im ridiculously in love with him and I feel like I single handedly screwed it up.

Well short update. He got mad after asking me a question and I was honest in my response. He ended up blocking me on all social media and texts... Then unblocked me to ask me to come over to his house when he gets off work. What in the world?!

Are you really asking what you did wrong??

I mean it doesn't sound like your dating. According to his actions it sounds like your a fuck buddy who caught feels and is being too nosy into his life...cue him not telling you every moment of his whereabouts. Which is really fucked up if you are together.

Are you exclusive. Have you defined the terms of your relationship?

OP, I can't tell which end is up in your situation. Do you have a history of flipping out on him? Does he have a history of flaking out on your plans?

From what you told us, it seems like he overreacted. Assuming there was a history of aggravation between you, though, maybe he didn't.

This couldn't have been the first time you guys had it out over these issues, right?
