Thanks once again for all your replies and support, sorry I couldn't get to a computer last night to write anything.
TPHW I like your questions, I went for a run last night and had a good think about those.
Yes I still think I got married too young, I think if I had my time again I would wait until this age. And some of it could definitely be the seven year itch, I had actually heard of that before but kept thinking it was just a joke. Maybe it's not so much of a joke as I thought.
I have definitely changed in the past 8 years, I feel I have grown stronger, more confident and I don't see the world as I did then. DH hasn't changed, and I find some of the things he does now quite hard to deal with, as opposed to then when I just let it pass me by.
But is it enough to go to Relate to? Would it be worth going just to say that I have changed and he hasn't? I am still not sure whether he would go either - it is a cultural thing really and it would cause him so much 'shame' that it would be difficult. However if it is going to save our marriage...
But I like BrownSuga's suggestion too, and I was thinking about this last night. I should figure out what I want, maybe get out and meet people that do the things I am interested in, and try to find something that we can do together.
There are still so many things to be worked on (and one of those is him not listening to me), but I think in the cold hard light of day I am not ready to throw it all away just yet.
Thanks once again for all your help, I was in a really low place yesterday and you helped me to see a different side.
