From all her responses, her tendency is very clear - she likes this great opportunity, she thinks this is a lifetime opportunity and she will regret if she doesn't take it. She wants to 'been there, done that'.
As a woman I totally understand her. It's not just ambition, it's not just vanity; Some people just want to try new things and new experience in life, so that when we look back we'd say 'This is my story. This is my legend'. (Even though there's a big chance we'd say 'I really regret...')
Just go with you heart - and I can see your heart wants this opportunity.
And who knows? Living apart from hu*****and for a while may make your relationship more exciting and sweet...
