Advice for trying to win my wife back?

Ok, so I am going to make an extremely long situation fairly short. I have been married 2.5 yrs now and my wife and I are currently seperated. While I was a kind, loving, giving and devoted husband during this time I was not attentive and affectionate. Because of this we have had a difficult marriage. Unfortunately my wife eventually looked outside the marriage for the excitement and attention I was not giving her. She had an online affair. We have been communicating and talking well, it is not a cold war at all, we talk all the time and it is good talking, but she says she doesn't feel anything for me anymore. I Haven't turned her on since we were married. We have been seperated for 2 months and now I am going back to see what there is between us. While we have been gone I have written her a love letter every day plus lots of emails and many gifts and made stuff for her. I love her more than anything in the world. I would like advice on what I should do when we are together starting next week. Any advice from people who have been here before? Yes, I realize she might just cheat all the time and that might be who she is. I don't think so, and I want to try and win her love back. I don't want to play games. I want to communicate and show her how much I do love her and cherish her. What would you suggest? How should I turn her on? I did take dancing lessons the whole time I have been away so I can take her dancing, she says that turns her on. Any suggestions would be greatly appreciated. Thank you!
