Short answer: Don't do it. Don't. No.
Longer answer:
I can totally relate to your story because something very similar happened to me when I was living in Europe. My then-girlfriend and I lived 1 hour apart and we both had our life going on (working, studying, etc etc). The only thing that differs is that we didn't live together. Yes, she was the hottest girl I had pulled by then because she quite the full package: breath-taking curves, amazing in the sheets, and on career path full of rewards. I was 25 at that time and I was almost sure she was 'The One'.
However, let's move to the moral of the story. I dumped her because she started acting very weird after we were moving things very forward like planning to move together and eventually marry in the span of a couple of years. She tried to get me back for two weeks but I was unmovable. I didn't think twice to get back together with her. Until 6 months passed.
I stayed NC for those 6 months and was quite enjoying my renewed bachelorhood partying and meeting girls (scoring some of them in between). Then I began noticing that while having sex I was missing the kind of sex I used to have with her. Totally mind-blowing...not only mind by the way. So I was basically missing her bed-freak traits and couldn't find them in the girls I was bedding. That hit me hard and I started to long for her to the point that I truly believed her words when she told I was 'the love of her life'.
I was missing not her as a person but the Idea of Her. I was missing the rewarding feelings of feeling loved, desired by someone else. I wasn't missing her as a person at all.
So, the great beta of me put in his mind that I had to take her back. She was mine; my lover, my future wife - I even thought about moving to her town. I did everything to reach out to me. Found her number - that I had deleted - in on smartphone. All along at this point I was deeply fantasizing about our incredible love story. So, I decided to call her.
Me: Hi Jane (fake name), it's Bnbprodu I want to talk...
She hung up on me.
Notwithstanding, I thought she might have been too emotionally overwhelmed and couldn't talk. So I told myself 'OK, I'm gonna visit her at her workplace'.
I knew her break time so I showed up right on time for her to be free.
I bought her favorite chocolate candies, showed up and convo went more or less like this:
Me - Can we have a word together?
Her - Listen, Bnbprodu, don't bother me anymore. I don't have feelings for you anymore.
'I don't have feelings for you anymore' said the girl who 6 months earlier told me I was her world, her everything and said she couldn't live without me.
From then on I went downhill and it took me 2 full years to recover, to not look at women as perpetrators of sorrow and sufferings.
Be wary, bro. Do what you think it's best for you but do it knowing the consequences you can face.
