Perhaps it may be a good idea to go away by yourself for a week or two and see how you feel on your own - I've been here and after spending a few weeks on my own I realised I had moved on without realising it for a long time - it was the right thing for me but it was not an easy decision and wasn't without a lot of heartache all round. Only you know what is right for you so give yourself plenty of time and space to weigh it all up before you decide - good luck with it all.
