this hurts, no doubt about it. It does not matter that he is a leo, all signs do this. Maybe he could not deal with the depth of his emotions, it is sad but now a days, men run from their emotions instead of staying and working it out. Maybe he felt guilty that he was happy, acutally it does not matter why he did that, all that matters is that you are hurting, and you will be for a long time. Of course you are struggling becasue it makes no sense, unfortunately people in love do things that make no sense, and those of us who don't act that way, sit at home and cry and wonder and analize and think, what did I do wrong, why, how, and make ourselves crazy. The only postive thing I can say to you is that better he did this to you now then after you were married, that would have hurt more. I know right now you can't see this, but to not return your calls, he is not as nice as you think he is. He did you a favour that it might take years to see. Of course you are not ready to date anyone else, because you really love this guy, I would recommend reading anything by colin tipping, he has a website called radical forgiveness.com, All you can do now is take one day, no one hour at a time, slowly you will emerge okay. You are a good person and you did not deserve this, the issue is his. Read, clean, walk outside, exercise anything to try to get your mind off of the pain. At least it is summer so you can go sit outside in nature. God bless and it will get easier
