Thanks for the response Jopap. But it's been 7 years that we are in relationship and we just had our engagement in the Philippines last May 2011 and we got a baby isn't that just enough tp prove that we have known each other in a very long time. But how about the sponsorship of my parents to my fiancé is they can able to do that or not? Many thanks to you

OK, but he should apply for EEA family permit, not fiancé visa. If he does, it will be turned down because you aren't considered to be settled in UK until you've been here 5 years, and only those with a settled status can sponsor a fiancé under UK immigration law. You do have rights under European law to bring your family member to UK, to include a fiancé under UK concessions.
As I've said, you seem to have enough resources to satisfy EEA permit requirements. You can still enclose a letter from your parents as safety net.
You need to describe your relationship to show it's durable (attach a letter outlying how you met, how you grew closer, engagement and plan for marriage), enclosing photos, travel tickets, skype log (just a few) etc.
I've just merged your two threads to make things easier!
