Sorry this reply is a bit late but anyway, a marriage is not valid in islam unless both your parents approve- unless of course they are not muslim or are muslim but do not pray as the prophet said (more or less) that what seperates a muslim and a kufr is his salaat. So technicall if they dont pray then they are not muslim. So if thats the case then you're marriage is valid.
What he is doing isnt right? why hadnt he thought of the consequences before he married you? This doesnt soud like something a mature practicing muslim man would do! What if the parents knew you were pregnant would it make a difference to them?
He needs to be careful about this word(talaaq) 3 strikes and thats it. I know of a couple who love each other however he couldnt control his tongue and had to divorce, they both suffered.
