Bright - my xh got close to his brother and sisters after he left . . prior to this I was the one who kept in touch, mainly . Now it turns out (according to him, at our last meeting in February) that they think he is autistic. Hmmmm Stay around a MLCer long enough and the cracks show.
Just before he left he got together with an old friend from way back (who I suspect encouraged him to leave, based on the lies that my xh was then telling spreading our marriage. Friend had been unhappily married for years, but stayed with his wife - she was impossible, I kid you - and I think he projected his own unhappiness onto my xh) Now he is back in touch with this guy, who has now separated from his wife . . . . .
Fwiw I don't think he is autistic. Just not very good at getting along with people these days. Maybe not ever and I didn't notice.
