I was always that way. Current BF is ten years older, but he's so much closer to my age than who I used to date that it feels normal. I only think of him being older when we talk about plans for the future. Otherwise, it feels like he is my age.

I look back at my years of dating much older (20+) people and sort of wish I hadn't done that. My 'best' relationships were usually with people 5-10 years older than me.
