Sorry to hold your feet to the fire again...but you said that your crimes were just "emotional". That is not true and I'm sure your H doesn't see it that way either. While you haven't actually explained your Skype adventures, you have said that you did things you were ashamed of. That broke the physical affair barrier. When you show a private part of your body to someone outside of your marriage even "only over the internet", that is still a physical affair.
And let me give you some food for thought...how do you know that the men that you did these things with didn't record what you did? You're going to have to live with the knowledge that you sent illicit interactions out over the internet and someone who knows what they are doing could have captured them. Also, some of these men could have "friended" you for that purpose. Predators use the internet to take advantage of women in this way but you are the one left facing the consequences.
I understand that you feel abandonded but the distinction is important. You weren't and you should remind yourself of that when those feelings creep in. Just like the emotional vs physical A question, it is important that you face the hard facts of what you did as ugly as it is because the more you allow yourself to wallow in denial, the harder it is for you to recover.
I'm not saying these things to punish you. I want you to get healthy and be able to move forward. In order to do that, you have to get real with what you did. Sometimes, it takes people outside your situation to help you see it clearly. You do sound much more like you get it now than when you first posted. Hopefully, you can use the clarity that comes with something like this to make your life better long term.
