PhantomThought gave me a random thought. Regarding Erin claiming that she could no longer take the horse because of immunization problems, that could have been another fib - It could possibly indicate that she planned to take off with CL when he finished his service and would not be able to take the horse. It would be interesting to know if any of her other activities indicated that she planned to leave 29 Palms soon. Maybe he had told her they would leave together and then ran out of options when the time actually arrived. She might have even been keeping that information from her texting friend. An affair can get you caught in so many lies you don't know if you're coming or going. This could have been irrespective of pregnancy. Just one possibility.
