I have seen to many people get hurt when they don’t respect when someone they care about has asked them not to contact them again. (After having all the usual post break up conversations, drama and such. There are usually at least three such encounters – three strikes and your out.)

If you keep calling and telling her you are getting help and going to change, bla, bla, bla… It might work for a time but the odds are against the relationship working out.

If you feel that you need to change then you must do that for yourself and not place that burden onto her. Perhaps once the work is done you might call her, however you must be prepared to learn that she has moved on.

If in time she should wants to contact you, you must be careful that your ready as its likely you will fall back to old habits.  You can’t step in the same river twice.
