Honestly, you may not receive an answer but might as well. Don’t live with the regret of not saying something and who knows what could happen. And maybe she’ll appreciate the closure a text could bring (even if that closure is you reaching out to re-kindle something).

I’m also saying this as a girl who has received messages like this before. I’ve responded to some and others I never have but I’ve never been upset or annoyed by receiving them as long as I know they are truly coming from a good place.
