birth plans

Hmm, sounds like you have two different and difficult situations!
Here’s what I think, but, of course, you should do what you know is right.

Ok, with your dad… Next time you talk to him about it (catch him or whatever), make it clear that if you ever find him doing it again you will tell your Mom. And then if you find out that he’s doing it still, tell her.
Don’t just promise not to tell if he will stop… promise that you will tell if he doesn’t stop.
If you do end up telling your Mom, make sure that you have proof, because she may not believe you.
What he is doing is wrong, and he should stop. It’s easy to go really down hill from there.
I know that it’s hard to be in this position with your Dad, but you need to think about the girls that he is talking to and their safety.
If your Dad is doing this openly, he must not care too much about concealing it. I suggest that you ‘get it off your chest and out in the open’.
I hope that it works out good for you! 🙂 Let us know if anything else happens! I’ll be praying for you and that your Dad would see his sin and repent! 🙂
(A lot of times men who do this are addicted to porn as well… if this is the case many men have been set free by going through the ‘Steps to Freedom’ by Neil Anderson.)

Second thing, your Grandmother will have to find out eventually. I have kept secrets before, though not a pregnancy secret, and I can tell you that it’s not a good thing.
Tell your Mom that you want to go to the wedding and that you want to tell your grandma before hand.
Whether she’s mad or not, your grandma will know sooner or later, and she won’t be as hurt if it’s sooner rather than later.
You could write a letter and have your Mom preview it before you send it or whatever. But I think that it’s important for you to be open with your Mom about how you feel about this.
Good luck, hun! I hope that everything works out! 🙂
