A few points from reading this thread...
-Dating is not a bartering system. Nothing you do for her means she owes you anything, and nothing she does for you means you owe her anything. Going on dates is about getting to know the other person, and testing the waters to see if you two are relationship material.
-Nobody has the right to expect anybody to change. You have the right to vocalize your opinions and issues, and she has the right to respond how she chooses to. But dating is not about changing someone. It's not easy to undo years of what's built-in by the way someone was raised and by life experiences. You would be better off finding a woman whose style of communication works with yours.
-Even though you may have intended the horse ride and the guitar, and whatnot, as simply being nice gestures, if she didn't respond how you expected her to, she didn't see them the same way. And she can't just change her feelings about those on a whim. Nor should she be expected to.
-As the pursuer, you pursue by the rules set by the pursuee. If I owned a business, I would be foolish to try to make people who are not my customers yet, or even who are, play by my perimeters. I have to reach out to them, and attract their business on their terms, and build in them the desire to do business with me. And as the pursuer, you can't put any more pressure on her than she's ready to accept.
-If you want her to pursue you, it won't be accomplished through spill-my-heart-out emails. You have to build in her the desire to pursue you, and this desire/attraction is not at all a logical thing, nor is it something you can try to guilt her into wanting to do. You have to be in demand, and she has to desire a supply of what's in demand. Another law of business that equates directly to relationships as well.
-When deciding how much you should try to impress her, it's better to slightly underdo it than to overdo it. Make her want to find out what's in Alexei's head. Make her want to dive deeper and go digging for herself. Give her the opportunity to want to get to know you better, find out more about you, and desire you on her own terms. Overdoing it, while it may seem sweet, blocks off the opportunity for her to work through her attraction to you in her mind.
-And as far as showing interest, yes, show interest, but again, ease into it. It's better to ease in slowly, even if it's a little bit too slowly, than to just cannonball right in. Again, this sort of mystery will build her curiousity, and make her think about you and what makes you tick... which equates directly to her thinking about you more, which leads to her developing feelings for you.
It might be too late to really salvage this one, but if it is, take this advice and use it the next time you find yourself dating a girl, seeing if she's a fit for you, relationally.
