Does Age Really Matter When U're In Love?

I'm a 19 year old female who's been in and out of relationships n who had been with this one person for over 7 years. None of my relationships seemed to last due to immaturity in the males. Once I decide that I'm gonna sit on da sidelines of dating for a while I meet my present boyfriend! He's so wonderful, and is my ideal husband! We've only been together for 6 months but it feels like 6 years. We kno each other so well. We still go out on dates at least 2x a month and go away with just the 2 of us once a month! Everything's wonderful, picture perfect....something like a fairy tale..my dream come tru! But it's one problem which I dont see as a problem but everyone else does! He's 27, turning 28 this year and already has 4 kids, and has had a bad past(thuggish) but is now over it..well most of it! I love him n his kids so much! I treat them as my own but the outside world say I'm too young to b a step-mom n too young to tie myself down to just him! Wat do u think? Wat would U do?
