I'm new to this whole Reddit thing and was referred by a post on the survivingfidelity. Where is the post that everyone read that bettered their marriages?

Here's a little insight . I was completely cold which turned my wife away. I know it sounds like complete BS but I was afraid of getting hurt . Well now she barely talks to me. We talked a few times and she gave me one last chance but she's still not talking . Is there anything I can do? I feel like she still wants this to work but how do I go about refixing this. What do I read?
