I think littlefinger will try to take Sansa's maidenhead, as he has repeatedly said he did, but didn't with Catlyn, and as Viserys tried to do with Danaerys.
Littlefinger trying to rape Sansa is so predictable that it almost seems...trite. It seems so clear and so obvious that things are headed in that direction that I hope it doesn't
happen, especially since Sansa's arc is full of guys fixing to rape her (Joffrey, Marillion, etc. etc.). Can't GRRM come up with something different for once? Really, though, Sansa's had so many near misses with rape that I worry someone at some point along the line is going to succeed, and if anyone were to succeed, it would likely be Littlefinger, whose sexual interest in her was telegraphed all the way back in AGOT ("Something about the way the small man looked at her made Sansa feel as though she had no clothes on").
...Of course, Sansa seems to be getting to be so messed in the head by Littlefinger's manipulations and sexual boundary pushing that by the time he actually does try to have sex with her, she might just go along with the abuse and not feel able to refuse him or fight back. Littlefinger is basically "grooming" Sansa the way pedophiles groom their victims to lower the victim's inhibitions and resistance and accept the pedophile's advances as normal, and it seems to be working. This doesn't mean that Sansa wouldn't necessarily fight back or resist, but Littlefinger's manipulations are aimed at taking away her defences, and these tactics are often successfully employed by pedophiles to ensure that their victims will not fight back or resist. It doesn't mean that Sansa's weak, any more than any victim of a pedophile is weak; it means that her abuser's a sick freak. Still, it could go that way, although I'm hoping GRRM does not go that route.
I think it will be here where Sansa kills him with the choker, not sure if he succeeds or not.
How would that work, exactly? She'd have to have a cup of some liquid on hand, get a stone free from the hairnet, somehow manage to dissolve it in the liquid, and force it down Littlefinger's throat, all while he's trying to rape her. I can't really picture that happening.
The use of the hairnet as poison would involve premeditated murder. It's not like a knife you can just whip out and wave around to defend yourself. I don't think Sansa is capable of coldly planning to murder someone ahead of time and then following through, even now, no matter what the provocation, even if it were to save an innocent child's life. She just isn't wired that way.
With all that said, the hairnet does seem to be a bit of a Chekhov's gun. Littlefinger's unlikely to get shoved out the Moon Door as the Eyrie is shut down for the winter, but him choking to death as Joffrey did would be a fitting punishment. I'm not sure how he gets there, though, if Sansa isn't going to poison him, and Sansa's the only one who knows the truth about her hairnet amethysts aside from Littlefinger. (Could Littlefinger be accidentally poisoned? Again, it doesn't seem possible.)
Simple forecast but profound, she will arrive at her wedding with Harry without Littlefinger dressed as Sansa.
I can't imagine her willingly marrying Harry without Littlefinger backing her into it. I personally hope she stays far away from Harry, since he is 1) handsome and 2) gallant/charming, and no good can come of that combination in these books. (Do we even know that his bastards were conceived through consensual sex? I'm not saying he's a Joffrey-level psychopath, but Joffrey could be plenty charming as well, when it suited him. Not that I'm looking forward to another would-be rapist in Sansa's storyline.)
