Hi
Your ex sounds exactly like my ex (not my ds's dad), except he didn't get aggressive, he was always the 'calm', passive one.
I know now that he lied from day 1. And not just about big thing, about tiny, small, completely irrelevant things. He was a compulsive liar and just can't tell the truth about anything. Everything I though I knew about him was just a facade. And it wasn't just me, he lies to everyone. Looking at his twitter page now there are so many inconsistancies, and lies revealed on there. He could never remember all his lies and was continually getting caught out, he didn't figure on someone like me who remembers stuff in minute detail I guess.
And I too tried to figure out how he worked, what was going on in his head. He wouldn't and couldn't let me or anyone in. He had zero empathy, and seemed to feed off the distress and misery his behaviour and actions caused me. In fact when I was happy and thought our relationship was great he later told me that he was completely miserable in that time. It meant I was constantly wondering if he was unhappy when I was happy and trying to figure out why. So I could never be happy again after that.
He didn't want to hear how I felt, complained he couldn't relax when he came home etc.
I would do everything I could to help him through the crazyness his ex inflicted on us while he tried to maintaine a relationship with his dd. He told me she was crazy and suffered depression etc to explain away her behaviour. I just couldn't understand it.
Late I found out he had lied about her, and to her. When I discovered the truth her behaviour made sense and, while I didn't condone it, I could completely understand her reaction and behaviour.
I know now that he is sick. He just won't admit it (nothing is ever his fault after all). I also see now that he runs away when anyone comes close to working out the truth about him. But it took me a long time to find that out and time away from him to get over the deep misery he cause me. And that I allowed to continue when really I should of cut him out of my life much sooner. But I kept thinking there was a decent person inside him somewhere, basing that on him be a normal person and before I knew the extent of his lies.
Your OH is lying to his colleagues too, about being separated. What else is he lying about, to you and to himself.
You need to cut yourself off and stop thinking you can have a future with him if he would just.....(fill in your choice of normal behaviour)...
You are feeding his bahaviour and allowing it to continue. Only you can stop it and start to heal yourself and make a life for yourself away from his destructive influence.
It takes time though. 1 year is nothing, I struggled for about 3 or 4 and we weren't together as long as you and have no children together either. So don't worry about that. It takes time, but you need to stop worrying about him and start thinking about yourself and your dc as separate from him.
I filled in this from my point of view (he kept telling me I was the one with the problem) and also what I believed my ex would answer if honest and the way I saw him from my POV. It made interesting reading -
