OH and I have had almost weekly tension-filled incidents for a few months now. We have been together for a year and I know we need to settle into each other, but it seems I cannot raise any concerns or talk about things without him going nuclear.
It's really easy to lose sight of what normal relationships look like if you have not had them. I know. It's been a real education for me these past few years :)
Your post struck me because I too have just celebrated my first year with the man I am with. We have not had to 'settle into each other'
He has an ex who is just about the worst human being I have ever come across, so hell bent on causing trouble, upsetting and hurting their own dc just to get what she wants, lies, outrageous claims, threats etc.
I have my own DC to consider and therefore I do have to raise difficult situations with him, not just about the ex, but with him personally too, and he raises things with me about things going on in my life and stuff. We don't row, we talk, we disagree on things and then agree to disagree if that is what's right.
My DS dad was abusive, he pretended to be the most wonderful man for the first year, then it all started changing, tiny bit by tiny bit.
On average abusive partners take 18m to 2 years to show their true selves. There will be teeny hints before then, but you'll brush them off thinking it's you with the wrong end of the stick etc.
Please read the book mentioned here - it really helped me understand the abuse dynamic, and helped me heal and learn.
The man you fell in love with is a fake, that is him pretending to be a nice human being. But he is a monster, he will only ever get worse.
No, you can't fix him,
No, he will never get any better or any worse
No, it won't be different for you. You are not a magician.
Don't EVER think, oh just because Hissy couldn't fix hers, doesn't mean I can't.
If I couldn't do it, nobody can. I tried solidly for over 4 years to ask him to be nice. I suffered mentally more than pretty much anyone you will have ever come across. I was trapped thousands of miles away from home, no family, no-one on my side.
there is literally nothing you can ever do/say/be that will make him stop being like this.
The sooner you cut this guy out of your life, the sooner you will start to heal. You will feel like the biggest prick on earth when you realise just how stupid you have been and for how long.
But I promise you this. In about a week you will start to feel better, safer and happier. Your stomach won't be in knots, the tension will go.
