infidelity

[hoosiermama]

Okay--specific question here. H has been on antidepressants for years--for anxiety, he thinks. (So have I--don't do menopause without it, is my motto!) A few months back--late January, February?--he switched to a different med. I wasn't aware at the time, but it's a relative decrease in dosage so that he's getting about 25% of the medication he was previously taking. In April, he began pursuing an old girlfriend, in May it became an emotional affair and now is probably physical; he announced a separation 2 days after they acknowledged feeling attracted to each other (which rapidly progressed to "it's fate that we're meant to spend our lives together").

Cut to the question--we have a sister-in-law who is a psychiatrist. His family, while initially concerned about his behavior, has now cut me off after talking with him; who knows what he's told them about me. Should I ask the SIL to try to find an opportunity to talk with him about the possible effect of the medication change on his behavior? He's had a few significant personality changes. I've emailed her--once, succinctly and specifically--to ask if I should be concerned about this, and she hasn't replied. I would have expected more objectivity from her, but again, she's always been closer to him than to me and I don't know how he may have painted this to her.

Any thoughts? Please?
