Seems a rather drastic way to learn Russian! Relationships are complicated enough without the added difficulty of being international. I would second the vote for VK I constantly get women contacting me there (maybe they are scammers I don't know). No doubt women receive plenty of attention too. Plus, It almost goes without saying, you should be careful about meeting people online.

What for lol? I think they are used to find sex partners for one night mostly. If you just want to talk, use VK.com. It's a very popular social network here. You will find everything on there.

Relationship based on language of emotions, but not information in speech. If you want learn language, unlikely it help you. If you want relationship, probably, you missed with website adress, as i understand, people learn languages here. Really learn.
