So it finished at 8.30, yet for an hour up to 9pm you were calling/texting him? almost half an hour before the networking stopped? Why? What purpose does that serve? Badgering him a full 30 minutes before his event finished? (When dh goes out, I always know to add an hr onto the time he says he will be home, just because. If he doesn't turn up, then he is having a good time & as long as I know where he is (he will text, on way home, still out etc) I really couldn't give a rats arse. Because he will be home eventually & he rarely goes out)
So no wonder he didn't come home, he knew he was in for an ear bashing & stayed out to avoid it. Then when he does come in, he is shouting. Is it any wonder? You started badgering him well before the networking even finished & you wonder why he is in a bad mood? You can't network while you are on the phone being yelled at!
If you were a man calling a woman like this, instead of getting support here you would be getting called a stalker, a manipulator, an abuser who wants his wife/gf with him at all times, getting accused of harassment etc.
My friend had girlfriends like you & it plays exactly how it reads here. They go out for one drink, she starts calling before his pint is even pulled, one becomes 2 so he can make a point that she isn't his keeper, she keeps calling, 2 becomes 3, she keeps calling, 3 becomes 4 because is he preparing himself for the fallout & may as well get hung for 4, as for 3 etc. She keeps calling, 4 becomes 5 because he doesn't even want to go home/see her now.
Meanwhile we are all thinking that she is some kind of stalker who can't let him have time with his mates.
As for "can't leave the house to drag him home", really? You would do this? If you could, you would go out, find him & drag him home? Just wow, really! Sorry op, but no wonder he didn't want to come home. You sound a bit unhinged & very controlling to be fair.
If he does it every time he goes out you need to plan for it, (even if it is only twice a year). Even if that mean you won't badger him, no matter what time it is & he doesn't come rolling home drunk out of his mind, vomiting etc, or after 12am. Because all you are doing here is pissing him off & in turn pissing yourself off.
