I have two sons about your sons age and we have also discussed this. Even though they both claim to be libetarians they are equally disgusted by this and can't understand why he just doesn't give guardianship to her parents. We have also discussed when, and if ,they get married setting it up so that I'm declared their guardian in case something happens. From this and past experiences it seems to be the way to go. They have both agreed. Hopefully, love won't get the better of them.
I've talked to my mom about this as well. Although I can't ever imagine being married again, stranger things have happened...but I'd want my mom in my corner if anything happened.
I said the same thing....give me or your dad guardianship. We'll fight to the death for life!
So far, no problem. No weddings in sight. ~sigh~
