I might stop saying it to her. I'm not suggesting you should, but I think that would be my inclination because I have self-esteem in the gutter and would go with my worst thoughts.
Texts are great in a way. You get to communicate your thoughts as soon as you have them. And then the other person can reply as soon as they are able. However, you can't read intonation and there's no inflection (and emojis only go so far...)
Hopefully, someone with decent advice will pop in.
In the mean time, I understand at least.
