Is it really that weird?
I met my husband when I was 16. We had similar interests, values, were at a similar level in terms of where our futures were going. My dad wholeheartedly approved of him. His mother and mine were less enthusiastic, but for reasons unrelated to age.
We're more than a decade out now, I'm still scratching my head as to why, when I tell people how old I was when we first started dating, they're often a little taken aback or even squicked out. There was nothing weird or exploitative about our relationship, it kind of unnerves me that people assume that must be the case. We were both intelligent, ambitious, developing young adults. We grew up a lot in those years, but we grew together and had a blast doing it. Our relationship changed and grew as we did. We're still growing and learning, I hope that never stops.
What's the big deal?
