This is not a situation I know much about, simply because I havent found myself in one before, with a filing marriage and new lover who then bailed out on you, and I'm very sorry that he did tht to you But, to answer your question, I do feel you should write him. If he wont take your calls or answer texts or e-mails.... yet you KNOW he is getting them, then write him, or even write a hand-writen note and make sure he gets it to let him know how you feel.. Just do it with class, dignity and in a way that shows your own strength and ability to move on, so he KNOWS that you are simply letting him know how wrong what he did to you was.

So, IMHO, you should write him, and even if you never hear back, at least you have said YOUR peace and know that you got everything you had to say to him off your mind and heart. Even if you get no reply.... you'll know he got the message and you have said your piece.

Go for it.

Best wishes and I hope you find peace of mind afterwards friend.
