I don't think it will make a difference, it's the relative maturity of the two people in the relationship that can make or break it. And yes, often times affiliations can make a person more mature (or vice versa!). My personal experience is an (im)perfect example: a relationship with a greek guy did not work well (among other things, he looked down on my own greek involvement...does that make sense???). The guy I'm dating now is not greek (though he has just as serious committments to an Order he belongs to), but a delightful, supportive young man. Go figure!
