Thanks for the replies.
Well I did go through a phase where I found it easier when on my own (especially once I sat down and said I simply can't and don't want a mobile glued to my hand in my spare time answering texts all day).
In fairness to her, she listened and had put a lot of effort in. And being honest, recent times have been better than the earlier phases. There have been recent times where I have thought "hmmm, I'm getting happier and more relaxed about a possible future" but I am not quite there yet, and well that's frustrating for her I suppose..keeping waiting....
About the phone being off...I have to say, and have said to her, I've grown to hate the phone sometimes, seeing it more as an electronic leash and something that constantly requires attention (I work on a chemical plant and I spend 12 hrs answering irritating alarms all the time....last thing I want is something else going off in my spare time)....
