Will, I have to say... I was close to leaving my husband (or kicking him out)... and the texts we exchanged after reconnecting were FAR more sexually charged than those you have posted... and before that, we weren't sending sexts to each other AT ALL. No innuendo, nothing.
Now, I will get the occasional conversation:
H: Cum here.
Me: Kids are awake!
H: So? You will just have to be quiet.
Me:.... you know me better than that.
All ending with me going into the bedroom with him LOL
Honestly, you could show her these posts, and say you hope to be able to have this much openness with her, in time. That way, she knows you would like it... but she has no time constraint.
