Glad to hear you had a good time with the family last night.
I am a veteran of the bad dreams about OW. I can tell you that in my sitch they have gone away now (of course as soon as I say that I'll have another one!). I told BF about it and both of us reminded me that it was just a bad dream. Just try to focus on a happy time when that happens.
If you love somebody, set them free. http://tinyurl.com/2empx2g
