when you are ready for this change in your life and willing to take the Responsiblity this fear will go away.
so don't worry , and try not to think about it alot, you have to be Positive and think about the good things that you will have in Your marriage
it okay to be afraid because its like buliding you own family so you need to be careful and live it in a right way ,but you can do it everyone can ,you just have to think good followed by a the right action to anything happen in your new life
I want from all to face their fear because it's only a feeling and its not real
