why would him winning £20m make him leave his wife and come to you, if he loves you and dislikes her, it shouldn't matter about the money.
Even though, I haven't done anything like this, I do however understand how you might be feeling. I returned to my home town 3 years ago (the town i'd left at the age of 17 and left behind my first love) from the moment I got back, I would look out for him wherever I was, at traffic lights, in town etc.. I remembered just how wonderful he was all those years ago.
Then one day, I was collecting my dd from ballet and I heard a voice shout me, IT WAS HIM ! still gorgeous and my heart skipped a beat, his dd was in the same ballet class.
Every week from then on, I never went to ballet without make-up on, looking good., he was all I could think about, then I noticed his details on friends reunited and e-mailed him, he never replied, and I am glad he didn't (he has far more sense than me)
Me and dh are relatively happy, he annoys me occassionally like they all do, but I soon realised that I was living and feeling how I did when I was 17 - it would never have worked and I'm glad I didn't persue it.
Is there no chance whatsoever that your relationship can be rekindled with your husband ?, I'm sorry to say, but I feel this man is just using you and enjoying every minute.
I hope you are ok
