You haven't seen your twin daughters for 2 months? Aww. That must be hard on you. They grow so quickly.
I have no idea which country you are in but I am guessing your lawyer is working on that for you.
I say congratulations to you and your girls. You seem like a nice guy. You didn't realize you were interested and falling in love with a married woman. Why would she hide that fact from an obviously attentive man? That is being deceitful right off the bat.
The above posters have given you good information. You can be the difference in these little ones lives. Birthdays and Christmas. All they are are just marking a happy time. JW..org wants to control every aspect of their members lives. You can influence them for the better.
Hugs to you for being a good guy. I am happy for your little girls that they have such a strong and caring Daddy that loves them very much.
