1. Don't tell your h not to contact you. The best way to handle this would be to ignore his calls and tms. It sends a clear and stronger signal to him when you don't respond. Actions speak/send a stronger message than words.
2. You've stated your feelings about the ow being at your daughter's wedding. Step back....it's your daughter's wedding....have her tell him. The message will be so much clearer coming from her.
Treese, you're reactions to your h's behavior/statements are knee jerk. He knows that he can push your buttons and you'll get angry and he really doesn't care. The button pushing is to get the reaction he wants to justify why he left you and is still gone. As long as you continue to say the things you do to him when you are angry, the longer he's going to be the "pod person" on the Mother Ship.
Learn to just leave him alone, do not expect one thing from him and if he does do something for you...thank him. He's a kid in a man's body and he needs to grow up. You are playing mother to his kid right now. Step back....it's not your job to be his mother.
Just leave him alone. Count to 10 if you feel your anger rising or just hang up the phone or walk away, but do not give him the satisfaction of seeing your anger. It's time to turn the tables a bit on him.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
