I don't see your texting as a mistake. My personal opinion is that it would be a mistake if she told you to leave her alone or had behaved in a manner that clearly indicated she wanted nothing to do with you.
In fact, I like it. You're not bringing up anything emotional or emoting to her and I think it was probably a good thing in the long run.
And her text today says it all. Feel free to answer her back with something light but meaningful. I remember telling my XH when he called me on our day, "It was a wonderful time and I'll never regret marrying you." He actually cried a little. So... saying something would be fine with me, as long as it's not bitter or angry. Or pursuing.
The 4th was really low key for me. My D20 went hiking on a 14er with her BFF and BFF's dad and then spent the night in their cabin. So D17 and I watched movies. Pretty lame. But remember I'm old. I turned into my parents, which is something I said I'd NEVER do. LOL.
Hang in there, friend.
