It is totally understandable that his behavior hurts at this stage. They have to have time and space to wrestle with their demons (and to see you less as one of them). Meds usually take about two weeks to have any effect and that is if the dosage is correct for a person's needs but hopefully you'll see a noticeable difference. Don't take the bait either! Great job not feeding into it. It can feel like you're not defending or sticking up for yourself. In reality, the best thing you can do for YOU is not get pulled further into conflict.
