BEen together for 2.3 years. My family LOVES this photographer and we have used her many different times. I had photos taken by her in 2002 when I just turned 18. It was my brothers and I. My step mom wanted to give my dad pics of us kids as a gift. Then my step bro/sis got pics taken. My step mom/dad. My brother and his g/f (now fiance), etc.
So I wanted it done. I think it's more about how you feel in the relationship. I mean just say I said I was engaged, how does that change anything? Either way the experiences are the same and feelings are the same (IMO).
