My advice to you is to get off the computer (including cutting yourself off of your habit of playing WoW for days on end, skyping your life away and sitting watching movies "in sync" and instead watch them with someone who is sitting at your side, with his arm around you and sharing your bowl of popcorn... Go out and find a real man that doesn't have another man hiding in the background that he is cheating on. A man that wouldn't NEVER do that kind of thing to someone but instead would break up with them if they are not happy in the relationship... not hang onto someone they claim to be miserable with but stay anyway and have fantasy sex over a computer with behind their partners back.
Why would you even want someone like that back? If they've done it with you then chances are very high that they will also do it to you when he gets bored with the routine sex with you.
You live in Serbia. Find a man there that wants what you want and is single and able to actually give it to you because he doesn't haven another man that he is committed to who lives with him thousands of miles away from you.
“The willingness to accept responsibility for one’s own life is the source from which self-respect springs.” ~Joan Didion
