Yes it is. Men and women can support each other holistically and as a whole. We just have to realize there are opportunists among us, and they are also unwell, more unwell than us. I’m not sure how to handle persistent, demonstrable undermining, but I’d gather after a couple or few instances, sadly, somehow segregating them if and until they seek serious professional therapy from experienced therapists trained in personality disorders with a proven track record of the behavior being curtailed over long periods of time. But I am not a therapist.
