There's a DIFFERENCE between someone being potential relationship material (obviously if you're interested in a relationship you should weed out the losers and the Love Avoidants and such) and being IN a relationship that has PROGRESSED to the point where you really believe you will end up married or permanent life partners.
Many people date a likely prospect for a couple of years before figuring out they're not really meant to marry. That's what the whole dating process is about - getting to know the other person. Most people would suggest you should date someone for at least two years before marrying - that's because it can take that long to really get to know someone.
Read Ginger's old posts - she was dating a guy she was really into, involved her daughter after a few months, thought everything was great - then he bailed on the relationship and her daughter really missed him. You don't want your son to suffer unnecessary pain of loss of a relationship with this guy. So unless you're sure that this is definitely heading towards a long term relationship I would wait.
But ask HIM - he might tell you he feels the way I do - and that would be a good and responsible thing. Or he might tell you he's not so sure your relationship will make it at all - at least you'd have an answer then.
