<human>: Give me the gist of the text in a nutshell

(For full text conversation see my post in Relationship_Advice. The link was up here but i was asked to take it down.)

[bad] Text summary~~

We are in a long distance relationship, going to separate Universities. Next year i plan on moving in town and I recently informed him of my decision. He didn't like my decision because i didn't ask his opinion, nor does he like the (girl)friend I'd be moving in with. He assumes the only reason I chose this move is because of the friend, when its not. I chose it because it will be cheaper, a different experience etc. I didn't consult him because I didn't think it had anything to do with him. He's not the one that has to live down here. 

He then says i "don't really give a shit" about him because i didn't consult him first. He always does this. If I make a decision he doesn't like, somehow it means i don't care for him. He says I don't make decisions as a couple. And i tell him it shouldn't concern him where I stay. Then he says (this is may favourite part) "I wanted you to put me first like a couple should". 

Then It just goes back an fourth, him- accusing me of not caring about his opinion/me not caring about him, and me- not understanding how/why me moving means this.

I want to try and fix this, we've been together for 3 years, but the longer this goes on the less i feel i should stay. Please help. Looking for advice on what I should do.

(Already posted in Relationship_Advice but only got a few comments. Looking for some more opinions.)

NOTE: South is a campus in town. The place I am hoping to move to is also in town and closer to grocery shops and more convenient as I don't have a car. Main campus is out of town and I have to rely on friends for transport into town for food, etc if I live there.
<bot>: BF doesn't want me to move in with friend I met at university and now has been blown out of proportion. Please help.
