whoop whoop ! Congratulations on your new job Gwen, wonderful news.
I'm sorry to hear you are having a down day - its fine, allow it to happen and let it pass.
Gwen - your m was real, the memories and love are real, your h has just buried it and has lost sight of his past happiness.
I know you miss him, it's natural to; I would be worried if you didn't. I find it comes in waves - the sadness, confusion and loneliness, I suppose the trick is to learn how to surf !
So on that note - try and distract yourself while these feelings pass through and then get back to focusing on what is important .... you and your girls :o)
