That's great news! Now go ahead and fall in love again.
Also, don't feel bad about bringing it up with her or asking her to do that for you. You may feel like you were worried about nothing, that you asked her to do that and it wasn't necessary.
And, she knew exactly why you were asking for it. And she did it anyways, because she wanted to build that trust with you, and she knew she wasn't lying.
If you have insecurities and need reassurance, don't be afraid to ask for it. Or maybe I should state it as, don't let your fear keep you from asking for it.
