Sorry you got cheated on bro. I went through the cold-hearted phase and eventually came out a better person. Hope you can say the same one day.

As far as the text, just answer her question. This isn't a shit test or trick question, so feel free to answer her honestly. She seems down as long as you indicate that you're down to keep things sexy and secret.

Lol women are just brutal. Definitely time to sexualise, don't want to beat around the bush given how open and direct she has been. Something like "Some much needed stress relief for you so you relax and re-energise to be a good wife and mother the next day"
