I am so confussed in my relationship!!?

Ok cut a long story short I met a hotel receptionist whilst on holiday abroad last year, we completely hit it off striaght away everything was rosie we chatted every day then i went back for a couple of weeks a month or so later and we had a absolute blast. One thing led to another and she moved over here both thinking it was going to be amazing. Thats where the troubles started because basically she was on my back all the time why cant i find work etc... I did absolutly everything i could to help, I even persueaded my Dad to go let her work for him. Which she agreed. We started to fight over absolutly anything and everything. Anyway a few month down the line we thought it would be best if she went home for a month. Even then every other day we would fight and i would get deleted from FB etc... and the whole i hate you so much and have met someone else, me and you are over (which is where we are at right now) and after this a few day later i would get messages saying I miss you so much. I know this girl cared for me a hell of a lot as honestly I dont think you would move you *** to a strange country to be with someone you didn't care about. I think she cared to much sometimes as it came across very controlling. Anyway I do love this girl and I know she loves me (even thou she says she feels so much hate for me at the minute) but I can't keep going on like this. How can I get this girl back but the way we was when first started????
