I'm glad you got out of the house and enjoy the beach w/your son.
Glad to see he texted and will watch your son this week. As for texting him about your sunburn, I wouldn't have done so. Why? Because if he were interested in your well being, etc., he would have inquired. Allow this man to come to you and that means stepping back from the urge to communicate w/him. He needs to "sense" that you are going on w/your life and that you aren't sitting there waiting from him to contact you all of the time.
The only way that he's going to be curious about you is if you don't share too much of your life. It's okay to share what is going on w/your son. For now, only communicate w/him about your son and financial issues, and emergencies only. He can't become curious about you if you are telling him about what you are or aren't doing voluntarily.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
