Might be worth it

 

I sincerely hope that nothing bad happens to the woman in this relationship.  So far, it doesn't sound like anything is going wrong. He has money, and he's spending it on a beautiful woman he met.  

Relationships like this have gone bad before.  However, even if it's short-term fun and doesn't go long-term family, as long as it ends cordially, why would there be a problem with it?  Relationships like this happen all the time.

My boyfriend has spent more than $1 MILLION on our trips around the world - we have visited 55 countries and ALWAYS stay in five-star hotels

And given that there are likely returns on investment in this relationship, she might be worth it.
