@paige1701,
Are you sure there isn't a reason for his sudden switch from 'lets get married' to 'now that we're married, I don't want to know you'? Like:
- he's actually gay, and you're cover
- he had to get married before XX years of age, to inherit
- You were on his bucket list / he made a bet
- some other equally stupid, but 'people do these stupid things' reason. etc
The main thing is - people just don't change overnight. If a change like your situation is sudden, then there's either been a sudden, drastic, negative change in life events... or they were being untruthful to you. If the change coincides with 'the happiest day of his life', then....
