Consensus on the other board is my marriage is over. Suggestions/replies have varied but main ones all say to go completely NC and then either:

1) File for separation immediately (although very slim chance, it may be my only option to have any impact on his A)
2) Wait until he comes back in July to give me some time to financially 'get my ducks in a row'
3) Expose the affair (again very slim chance this would have a positive impact--no one really important or influential in my H's life I could expose it to)
