M - Your H is acting like a huge A$$. If I received that email, I would be appalled. He is living in delusional land at the moment.

I would respond with "I received your revised proposal and have forwarded it my L." I don't even think he deserves the "thank you for your thoughts."

As for the medication, I would make sure you D brings it the next time she heads to H's house. Your D needs the meds. While your H should be able to figure it out (considering he wants them 50/50), I would just make sure she has it this time. No need to punish your D because you H cant figure it out.
