Hi ahmedwaqas,
How was your trip to Pakistan? I hope you had fun? I was asking myself what happened to you since there was silence of 5 or 6 weeks. Alright down to business now:
First of all, sending those things at this stage might not help because you don't have any sign that CIC is doubting your relationship. You may send them if you feel it's going to help, however the stuffs you want to send are only good to made a decision on eligibility. Your GCMS notes will shed so much light when they come.
Secondly, your age difference is not that huge but it needs solid proofs that this is a relationship of love and not relationship of convenience. Plus CIC would be interested to scrutinize your relationship in much deeper way like: why this young man wants to marry 1) a woman who is 6 years older than him? 2) a woman who has 5 children of her own? They would like to take time to find out if she is covering something. E.g: did this young man pay money to this woman? Is there any concrete proofs which shows that this relationship is secure? So this might be the reason why they took a bit time to finalised your application, but stay positive because 2016 will come with its own realities. I wish you ordered your notes at the time you left for Pakistan, you'd have more light by now.
