Thank you all for your replies, you know I never even thought that he may not have got married!!!
I didn't go to the wedding and wouldn't have done if invited out of respect to her as she was a bit funny with me just because I was his ex. To me there was no issue and no threat but thinking now I think she may have sensed a threat from him. That was back in 1998 though!
Whever I ask him about married life he either just ignores the question or comes back with something like "not too bad".
China, hey hon, at first my feelings were all over the place. He always treated me like an absolute princess, makes me laugh and feel special and he was devasted when I ended the relationship although we stayed friends.
Now though it's just upsetting and horrible and seeing the way he's treated his wife (if there is one) has put me off for good as well as the fact he lives hundreds of miles away and still seems to live like a student (annoyed me enough when he was one as met him at uni).
