I have a different perspective on this type of situation which might land me in flame city here lol. First thing..
What a berk!!
However i am not one to talk cos sometimes my DP opens his mouth and not very nice things come out. I put it down to being a dumbass and insensitive nob.
I do put up with it for a bit then i snap and say something 'You're criticising me again, you're speaking to me like crap again' ect.. and he looks mortally wounded as if he didn't realise (and seriously, i don't think he DOES..he and i were brought up in families that are quick to criticise and verrrrry slow to praise) i have used this to my advantage, and praise my kids, say nice things to people as often as i can, think before i speak "Is this hurtful, do i really need to say it, would i like it if it was said to me, is there a nicer way to put it," you get the idea.
Things are slowly improving but it is a hard habit to break in someone who has been, IMO.. emotionally abused during his childhood.
I am willing to work on it because i can see the person in him that is dying to come out.. and he is willing to make the effort.. with relapses lol! So it is up to you, do you feel able to talk to him about it and tell him how he makes you feel, do you tell him to sling his hook, or do you continue to put up with it and hope he doesn't turn into a control freak who feels he is able to 'comment' in every which way he likes about you without thought, or fear of repercussion, maybe graduating to becoming more and more abusive?
My DP would never .. and i repeat, never, lay a finger on me in anger or violence. He is simply not that type of person and trust me, i have known a few, brought up with them beating my mum, had my own experiences.
So i can't say 'If he ever' blah blah, because that would be admitting there is a chance that he might.
The ball, as it were, is in your court.
No one can tell you what to do, just offer advice. Some of the comments here are great, i love the one "Well i hate to tell you you have a small willy" But would not go down that route personally as it means being as bad as him, thereby basically validating what he does to you.
