No, I'm sorry May, I don't think that is the truth. You aren't looking too much into this. You have left, and he still hasn't made an effort? What is it going to take for him to WAKE UP and realise what it is he is losing by behaving like this?
I'm sorry but nothing you can do will make this guy grow up. My ex also used to say "All I want is for us to be a real family" "I just want to make it work" etc etc ad nauseum.
What he means is, he wants to go out to work and out to the pub, and you sit at home, do all the housework and keep the children quiet and clean for him. Occasionally he can bring you (ie "his family") out as a trophy to show the world how wonderful he is. But other than that, you're there to keep his house tidy, make his dinner, and provide sex on tap. This in his mind is a fair exchange for the money he earns at work, what else could you possibly want? He will provide you with anything you need in the world!
Sorry, I know this is hard to hear. But honestly, do you want the rest of your life to be like this, with no emotional support? It sounds very lonely and utterly depressing to me. I was told the same by the way, that I had PND and if I went on medication everything would be fine. What bollocks - no medication in the world would have changed the fact that my ex was an arse. Yes, I probably was depressed - but it wasn't hormonal, it was a perfectly rational response to a horrible situation.
I hope you are okay and I wish you luck. Stay strong and think about what you really want - and keep posting. Keep yourself educated about the stages he is likely to go through to convince you to come back, because you want to be prepared. Mumsnet is famed for its "tough love" but it really is wonderful advice. Think of it as coming from a big sister - might be a bit blunt, but in your best interests.
(Also, it doesn't matter if you use the abbreviations or not, but a lot of posters here find text speak irritating or difficult to read, so it's considered impolite to use it. You said you are new so I thought I'd point this out!) :)
