Thanks backon. We did watch a movie together the other night which was good. He's hot and cold all the time, so sometimes hard to talk to, sometimes really easy like it always used to be. I'll keep sending him good vibes and doing everything I can.
I do feel I had a setback just now though. I overheard him having 'guy talk' with a friend; I couldn't hear what the friend was saying so I went downstairs and told him to leave because his words hurt me. My emotions just took over...he was really cold like I have never seen before as he practically told me to 'do my own thing' and that I had misunderstood everything. 
I gave him ten minutes and apologised, told him how hard it was for me to hear him talk like that as he never used to. It really hurt because he was talking about a redhead which I knew when I met him he had a thing for. I was never threatened by that until now...When I apologised he changed for a minute into the nice person he I know he is and apologised back and said he knew it must be hard for me to hear...
I feel as if I've undone all the good of the past week. 

Thanks Serendipity. I feel in the last week I have made nice progress; lots of reading and implementing structured techniques everyday. I treat him as I did before I pushed him away - never a doubt, always trusting. I've accepted that my reality has already been created now

Yes, still some moments are difficult but I am learning every time to turn things into the positive. I'm making more of an effort than ever to enjoy my life on my own, and enjoy the time that he and I do spend together, which is usually very comfortable and friendly.
