I am newly divorced.
honestly, it sounds like infatuation - you held on to feelings for all these years, but how well do you really know him. But it doesn't matter, as other poster said, he has moved on. So you have 2 choices, you can sit around and hope some day they break up and he runs back to you, or you can put yourself first and find a man that you can truly fall in love with.,
I think only time can tell if you truly love him but I think that he has moved on. And sometimes we hold onto these feelings because of the idea that we created how he is the one for you.. I bet you if you met someone else that you really like that you would forget about this guy.
