Who doesn't love some old-fashioned romance and gentlemanliness from time to time? A definite sign that your man is totally in love with you is if he treats you like a proper lady. You'll know you've got a real gentleman on your hands if you never have to worry about carrying heavy things, opening doors, or handling any kind of physical task.
Of course, as a real gentleman, he'll gladly let you take care of your own bags if that's what you're after. He may also do cute, old school things like ask you to dance at a hole in the wall jazz bar or order a gorgeous meal at a restaurant where he knows all of the best food options. When you're dating a man like this, don't be surprised if a dozen roses miraculously appear at your door one day.
