First off,
I'm sorry that you are going through this. I can't imagine how you are feeling. It's easy for all of us to try & give you advice but ultimately you need to do what is best for you and your precious children. If you want to tell your parents, tell them. It's not fair that he tells you who you can & can't tell. This is extremely emotional time & you need your family's support!
Remember, ultimately it's YOU & YOUR KIDS (period).
Be strong.
Have faith.
You are young and beautiful and you have your ENTIRE life ahead of you!!!!!
God put you on this earth for bigger and better things!!!!!
You call the shots!!
