I think mlc-ers have an easy path to get family onside.
No-one would ever believe the truth of what has happened, so the re-write of history that forms part of the script is what gets accepted.
It must be that their spouse was controlling, disgusting, unable to be lived with one moment longer, even for the sake of the kids. Whatever else could have led to an outwardly happy family being broken up so quickly and with such finality?
And the poor mlc-er, how he has suffered and for so long. And what he has been reduced to - he has no home, no money, has given up everything....
Again, who, outside of experiencing it themselves, would ever believe what has really happened?
Having said that, IDK if I could cope with not responding - briefly and calmly.
I have, in the past, ignored such outbursts from others who I feel have the 'wrong end of the stick'. I find it festers and makes me feel resentful.
I am also feel sick of 'covering up' the whole notion of mlc.
If only we could say "my spouse is suffering from a classic mlc. I suggest you do some quick reading on the topic and find out how devastating this emotional turmoil/identity crisis can be to those around them before you judge me."
