Ambivalent, I'm very sorry Christmas was such a mess. As for your daughter...what was she thinking in trying to get your phone to get the number? From your posting, in my opinion, your daughters do not have any respect for you or your privacy. There is a reason why you didn't want her to have the number and now, well...I wouldn't trust her. She's going to have to work very hard to regain your trust.
Now, about your "Dear John". I'm glad that everything is out on the table. He will not change unless he gets therapy and comes to understand why he needs so many women in his life. Your story reminds me of the current movie out there called "The Other Woman" w/Cameron Diaz. John is lucky, you three could have done some serious damage and not just split the money up. Hard to tell just how many more women he has out there.
You have to keep your focus on your exams, divorce and other things in your life. I think you need to consider putting dating on the back burner. In my opinion, you've got to get your baggage cleaned up and get your life in order before contemplating bringing someone else into your life. Take things slowly and give yourself some time to heal. Learn to live life on your own first and when all of the divorce stuff, moving and yes, a job, are taken care of, then consider what may come next, i.e., dating and one day finding someone who will want to share his life w/you on a permanent basis. Trust me, the frogs will still be sitting on the lily pads, waiting to be kissed, when you are more settled and healed and ready for a healthy relationship.
Good luck with your exam next week. Travel safely and try to relax this weekend. You need to be well rested and focused for this test.
