OK ladies, if you want a guys opinion. November isn't that long of a time and assuming that it will get serious is a bit much. With that in mind, something very impersonal should do. Considering you don't know much about him is another reason. Though there is much more I can say, I suggest a gift card to his favorite place to eat. If you don't know this, then you don't know him well enough to give him a gift at all. You are not obligated to get him anything since you've only been dating a month. If you insist then make it impersonal. Or you could make him a really good meal, with out the fun. Worked for DW and that was 34 years ago.
With all due respect and as the father of three girls, I never understood why a man or woman would go to another man or woman for advice about a man or a woman. Does that make sense? If I was dating a girl and she gave me something personal after a month? I'd dump her and I have.
Had a girlfriend once who was going around telling everyone we knew and her family we we're getting married. Her mother and sister came to visit me by themselves to talk wedding and were shocked when I told them we weren't. Heck I hadn't even said those three little words to her. Dropped her real fast.
A smart woman gets a man to marry her buts gets him to believe it was all his idea in the first place.
Wish you the best
