Trying to deal with emotions.

Right after David deployed I found an email he wrote to a girl that made it seem he was emotionally cheating on me. We worked through it and he promised to not contact her or have contact with her again. Two days ago I found out that they were chatting on Yahoo messenger and even went on Skype to talk. It did not dawn on me at the time but they did not exchange user names for Skype which means they have talked on Skype before - even though he promised to not have anything to do with her - and I am really hurt over the whole thing. I feel as though he feels talking to someone who says that she will break up his and my marriage is worth more than our marriage. Now he is on his way home for R&R and I am having mixed feelings about him coming home. On one hand I am so excited to see him again, I do love him very much, but on the other hand I am scared to see him because of all this hurt inside me (even though I love him, sometimes I do not like him). I don't know what tomorrow will bring, either the end of my marriage or a resolution to some of our problems. I no longer want to be hurt which means he will have to make up his mind on a couple of things. I am worth more than empty promises and lies and it is about time he started acting like that.
