I think her next time at sea will give you a great opportunity to really focus on your own goals and provide a time of healing and reflection.
My X was deployed during our separation and I was relieved! It gave me time to see things from a more objective perspective.
The only thing I would add to your whole sitch is that make sure GAL/180's etc are not about her. I.E. these are things for you, because women are very observant...if you learn spanish because it's her language, that will feel like pursuit.
Just an example. GAL shouldn't be about winning her back.
She will return to you or not, but it won't be because of something you do. It will take her working on herself.
Wishing you much healing during this. Glad you are sleeping and eating again! Focus on those kids as much as possible. They leave way too soon! (My youngest is home for another week, this is his first year at Uni). Glad to see you going fun activities with them. You will never regret time focused on them!
