<human>: Can you succinctly summarize the text in 1-3 sentences?

Yesterday I decided to call it quits with my girlfriend of a year. She is a fantastic person and cared about me a lot and I cared for her very much so too but over the past four months or so I feel like we had been losing our connection.

I work midnight shift at my job and she works very early mornings. She has horrible anxiety and because of this, she can't drive on her own so I would always be the one to have to pick her up and take her home which meant that we could only see each other on my days off which was fine when our days off matched, well when that changed, so did the time we spent together. Over the past four to five months we only saw each other once a week and occasionally once every other week. This began to take its toll on the both of us and I was the first one to say something about it and well over the past few weeks we had been talking about the future of our relationship and such and last night I decided that it would be best for us to not be in a relationship at this time.

It's really bothering me more than I thought it was going to honestly. I have been the one to break up with my significant other only once and at the moment, it's  getting to me because she is a very sweet girl who cared about me a lot and did everything I asked of her and I know that because of her emotional issues it is really hurting her right now. 

Some words of advice on how to better handle this would be appreciated.
