Change your number sweetie, and move on with your life. You are well out of it, though you may not feel that way now. In my opinion, you are much luckier than people like Callie who are still stuck with the addict in all their full glorious drama and she now has to decide whether to take him back and continue to do the codie dance for what could be years of pain and loss and financial and emotional ruin (Callie, free yourself, Baby!).
You can take this chance to move your life focus back to you, because your wife has made this decision for you. And it is a good decision for you to be alone for a while! You have a chance to learn about you and what you like now!
It is unkind that she is filling you in on the details. Stop listening to this, for your own sanity, and move on. Give yourself time to grieve and work on your self-esteem before you pick up a new relationship. Keep up the Alanon. It works if you work it, brother!
Love,
KJ
