My H was pretty much the same. More than happy to chit chat when not with OW; but when she was around he was very abrupt and darn right rude.
It is just so two faced.
I would not tolerate him talking to me one way when around her and another when he wasn’t so now I no longer accept phone calls or texts from him, nor do I send any.
We communicate fine enough through e-mail. (Even they are few and far between)
If he misses out on important information about our son that’s his problem.
