Ye Gods !! I can't believe you're thinking of marrying a man who even before he's got you up the aisle, is telling you he's going to dump you if you don't give him a child within a year. He sounds a thoroughly self-centred individual who is just using you as a breeding factory. For heavens sake, if your relationship is already rocky as you say it is, dump him and find somebody who will value you for the individual you are, rather than the womb he wants to temporarily rent. Are you so low in self-esteem that you are prepared just to stand by and be treated like this. What will be his next demand, I wonder, if you do become pregnant? He's already made it crystal clear to you what he wants you for and that obviously doesn't seem to be love, mutual respect and permanent commitment whatever hurdles you may jointly encounter. If you don't have the common sense and courage to break off this relationship now before you're unfortunate enough to get pregnant by this man you will probably get the future you deserve. And sadly it probably won't be a very happy one.
