Love sick - it appears things wil not work out well in Spring Torrents

So you just know things will not work out for Sanin, the young Russian traveler who falls instantly and madly in love with the Italian beauty, Gemma, while passing through Frankfort. They're both in rapture, but reality intervenes and Sanin realizes he needs to get some money together in order to marry Gemma (a baker's daughter) and support her - so he seizes on the idea of selling his estate back in Russia. By chance - or so it seems - he runs into an old school acquaintance who's passing through Frankfort, and the acquaintance notes that his wealthy and beautiful wife may wish to buy the estate. Sanin and the friend - another truly obsequious and narcissitic character, Turgenev is really good at sketching this, in particular because he does not overdo it - head off to see the wife - and you this will clearly not work out at all. She's a very strange person, doting over her husband in a weird sexual way - she asks him to comb her hair - and he's such a dolt, you have to wonder, as everyone does, why this wealthy beauty would marry him. I'm just at a point where she begins negotiating price with Sanin, and she takes umbrage at the idea that she may try to get a bargain price. She also makes clear that she's a peasant by birth, and she asks many pointed questions about Sanin's fiancee. So what's her game? Is she flirting with Sanin in some way? If so, why? Out of pure evil? Is she trying to rip him off in some way? That's not obvious - but what is obvious is that Sanin is making decisions way too haphazardly, he's a fool in love, and that there's something fishy about his so-called friend just finding him by chance. Of course we know that Sanin does not lead a happy life because of Turgenev's introductory chapter, in which a much older Sanin ponders is depressed and mournful - and then discovers a garnet cross, which sends him mind back to his courtship of Gemma. We don't know, yet, the significance of the cross - I'd thought all along that Gemma had given it to him but maybe not, maybe it's the faux peasant seductress, and maybe it ruins the pending happy marriage.
