Even though you didn’t directly give her money, you got her diamond ring, saved ton of money to support her, redecorated snd customized your house. And you aren’t even a couple!
She costs you money all while she lives comfortably married to someone else. She’s not in danger yet chooses to live a life of lie and deceit. And I’d refrain from calling her fiancée and talk about engagement. You can’t be engaged to married people
Them sleeping in separate bedrooms doesn’t mean anything. It’s not uncommon and doesn’t make them less married. Him being older is irrelevant too. You are older too. Would it justify her cheating on you too? A woman is dishonest. Meeting up with men while her husband is at work? Gross
Why’d you want to be with someone like that
