Hi Adifferentname, well everybody has said it all and I second the general consensus. I totally agree with the summing up of Cogito's analysis too.
Nothing you describe, adifferent, is normal whatsoever. I am still totally amazed at the sex issue! Surely you've challenged him on this because I am aghast tbh. This standalone topic itself, smacks of some much deeper problem with him, that's for sure, and would have been a red flag for me years ago. Aside from the "honeymoon period" you had at the beginning, you've only had sex twice, and he's explained his behaviour away by saying he has a low sex drive? He's never seen a Dr about this problem? This alone would surely finish off most marriages, if left unchecked.
Do you think he is a narcissist? He does sound very arrogant and self-absorbed. It also makes me wonder what his previous relationships with women were like, prior to meeting you....
It's extremely worrying the treatment he is doling out to your daughter ( as well as you obv ), and his general opinion of other females. It also sounds like he may intend to mould your son into his "mini me", if there is a huge disparity in his behaviour towards your kids. More red flags you are right to be concerned about. This cannot be allowed to go on. And the swearing like that is a sheer disgrace.
May I ask, is he a hands on dad, and do you enjoy plenty of family time when he isn't holed up in his room? Because this needs to be challenged obv too, if the answer is no. I am flabbergasted at your comment re a bed for your daughter btw!! OMG!
He does seem to have a serious power complex but his entire behaviour will be very damaging in the long run. Is there nobody else, colleagues of his, family etc who know of his strange behavioural traits and can offer any incite as to why he acts like he does? Were there problems growing up for e.g? I am amazed you've lasted as long as you have to be frank!
You need to regain the power balance within this relationship but, tbh, the future for your marriage does not look terribly bright. He doesn't sound the sort that would have an epiphany, when you tell him all the problems with his behaviour that you have told us. I can't imagine a huge turnaround whereby he takes all the facts onboard and changes his personality/behaviour to that of a normal, loving husband/dad.
BTW is he affectionate with you and the kids? Does he buy you all gifts on occasions, or "just because"? Does he pull his weight around the house re chores? Just trying to get more insight into the background, really, and what he's like day to day.
Best wishes in what you decided to do next, though. X
