I'm SO bored. Have been for quite some time. Leaving isn't an option (am pg with twins) and I don't have any other problems with DH apart from sheer solid boredom.
He's a bit of a bore about his own subject, and likes delivering monologues. But unless he's doing the talking, he's not really interested in conversation.
When sitting next to some internationally famous fascinating giant of public life at dinner [this happens because of where we live/work], he will deliver a monologue about his day involving catching two trains, visiting colleagues and picking up his bike from the bike shop. Giant of public life will then turn away without another word and DP will conclude that dinners are boring and he'd rather be at work.
He's also not really interested in stuff generally, stuff that interests me (or in my topics of geekdom, though I do kind of understand that). He doesn't read newspapers critically, doesn't read anything else at all unless it's work stuff, and geeks out into his own world if I try to talk about anything else, or put on the TV, or suggest we go and do something that isn't work (or the sport he plays).
Attempts to get him to join clubs or go to museums or go on interesting city breaks (or interesting non-city breaks) are met with polite engagement that lasts as long as he thinks i'm paying attention.
AAAARRRRGGGGGHHHHHHHHHHHHHH!
