Aimee, you don't owe your bio-dad anything.

However, if he's had a relationship with your half-sis, and if you don't know whether that relationship is good or bad, you might want to send him one last note, telling him that you're going to contact half-sis, and if he wants to break the news first, he can do so, but if he chooses to NOT break the news, you're still going to contact her.

If he has a decent relationship with her, she might want to hear it from him first.

I'm not saying that you should decide whether to contact her based on his reaction; definitely contact her, no matter what. But maybe give him one last chance to do the right thing. Give him a time frame; like Trudy said, tell him that you're going to contact half-sister in March no matter what, so if he wants to be honorable about it, he has until then to tell her.

Amazing Aimee - good luck!

Teppy (and everyone else) is wise.

Beth says what I was going to. If I got such a letter, I'd want to respond quickly, but probably not by phone. Good luck with it. She's a lucky person to be related to you and the amazing Miss Em.

The dentist said that the stitches where my tooth was would come out on their own. Most have, but one is driving me insane and it seems to be camped in there for the long haul.

Also, I'm making the ATK recipe for pulled pork in my crockpot. I have been smelling it all day and I think I'm about to eat a television remote and a couple of pens.

Something like:

Dear Bio-Dad:

I've recently moved back to Michigan and since I last wrote you, I have gotten married and have had a daughter. I would very much like to contact Sister, but wanted to give you the opportunity to break the news, as it were, to her about having a half-sister. I will be sending a letter to her at the beginning of March.

Hope all is well with you,

Signed,
Daughter you refuse to acknowledge and now you don't get to know your totally kick-ass granddaughter, you halfwit.

I would change the wording of "I would very much like" into something more definitive to make it clear that he does not have control over your actions, only his. Like, "I am going to."

(Whoops, hit post early.)

But other than that, I think it sounds great.

Is there a reason you'd be waiting till March, Aimee?

I think I'm about to eat a television remote and a couple of pens.

Funny, I think Mr. Peabody is posting for Ginger!

Is there a reason you'd be waiting till March, Aimee?

I just picked March randomly, fwiw.

Oh wow Aimee - big day! Good luck, and I hope it all turns out for the best.

It seems like about a month would be a good amount of time to sit with the information and give him a chance to let his other daughter know if that's what he wants to do.

Aimee, what will you do if he responds that she already knows about you and doesn't want to be contacted?
