The only paragraph that I would change is that "stop having sex" statement. IMO it might sound better to say "back off of sex", take the pressure off each other. Then if the time feels right, we may find comfort in each other's arms while we are working through these difficult times we are going through.
On the timing, if she will have time alone on her trip, away from the kids. She would have time to reflect on what you have said. Otherwise wait until she gets back to deliver the message.
