Quote:send her emails, send her cards, send her flowers, call her.
.... and please, send her long, hand-written letters that explains just what a mistake you made... how you really did love her... have always loved her and wished from the moment you said those awful words about not loving her, that you could take them back.
Be sure to say that you made a huge mistake... that you'll do whatever is in your power to make it easier if you two can get back together and you love the family that you and she made.
Any relationship can be salvaged if you love each other and want to make it work. You may have to be humble, you may have to voice some feelings that you don't usually do, but I have confidence if you are sincere and contrite, she will come around.
Begging is not too far for you to go at this point...you really did screw up, you know... and remember, when you argue and fight -- it is best not to go overboard.
