Awesome! It sounds like you put the appropriate amount of thought into the situation and it's best when you say it naturally like you did. Succumbing to pressure is never the answer, and the fact that you held out is good.
I remember the first time I told one of my ex-girlfriends that I loved her. We always used to say, "I like you" or something silly like that. One time I said it without meaning it and she said, "did you just...?" and I said, "yeah I didn't... I mean... Uhhh..." I don't remember exactly what happened after that but I remember feeling like the silliest person in the world.
