Takamamash: I don’t know anything about rules. I’m not so Yeshivish sociologically speaking (even though I am hashkafically) and a lot of my dating has been with guys who were more Yeshivish YU/Modern Orthodox Machmir types. I wasn’t talking about rules so much as comfort level. I think I would be uncomfortable if a guy gave me flowers before we were engaged. I feel like a guy giving a girl flowers is very meaningful and should only be done after engagement.
BUT, I really am not qualified to say much on the topic since I never went out with anyone at all seriously, so I never went out with anyone whom I would have wanted flowers from. So I can’t really say till it happens, BEH.
