Fine 4s..... You have to let go. How about if your "ex" marries the current women he is with and not you/me? You still hold on to those feelings and he is all married to the other woman.. That is why I say you have to clear the old energy.
Then also, when you hold on to feelings for an ex... You are blocking the new person in your life from coming through..
No one wants to compete with old relationships..
