Carol, Gossip, Dahlen, Imp, Less, Kiwi, Poppy and I :) are all right on the money - he is not, nor after two years will he be, that into to you.
In my head - I see us together and having kids etc
That's the only place it's likely to happen :( the fact that you do have that in your head is what's allowing you to excuse any disrespectful behaviour and frankly I am willing to bet the farm there is a lot
All of it carefully constructed to keep you but not too close just where he wants you. There is no way to say this without sounding patronising but I feel very sorry for you because I know from bitter experience that this guy will be an utter nightmare to get rid off.
He has everything he needs without any responsiblilty to you and ime emotional manipulators like that will pull out all the stops to get what they want.
My X did introduce me to family, friends etc after I said I would leave - thing is everything was that same long drawn out process and frankly relationships require work but not all on one persons part and certainly not all the time.
Be prepared for tears and protestations of love and 'doing better' etc - unless you want to waste more time and shed loads of energy - don't fall for it.
