Update: Thank you all for the comments <3

I have reached a point in this now where I am no longer sad. Im not crying anymore and am not desperate to have him back in my life.

I would still like to ask him if he will put in the effort to fix things (being committed to me and sticking by me when things get tough, skill building, taking my concerns into account, etc).

But mostly,
I can understand why a person would get fed up with someone who is constantly jealous and wont allow him to see his friends.
However, all of my outbursts have been for a good reason.

He continuously holds it against me for getting angry when he went out with his friends these two times (when he was being distant and I had finally heard from him at 1 AM when he got home from the bar, and when he ditched me on "our day" to be with people hes never hung out with before). I need to tell him that that is not okay.

Im more and more concerned about this "good friend" of his and I made up a list of "I dont feel okay when. . ." to bring to his attention.

The biggest reason im not as eager to be back with him is because of what he in vermont. I saw on his reddit page that 3 months ago he is looking forward to "proposing to my gf, getting married, and traveling the world." In vermont in august (i think?) he said if someone leaves a relationship when it gets tough, they will be in a new one every year. He is going against himself and the fact that very recently he wanted to marry me and a few short months later, he broke up with me. What gives?

I think its possible he is afraid that when he marries me he will lose all of his freedom.
There is only so much I can tell you guys that really detail how horrible I am to him when my jealousy strikes. It isnt just "Im jealous" its "f you" and terrible rage and violent words.

While I can easily see that the way I express my concerns to him have driven him to this point, the fact that I have those concerns in the first place are valid.
