Really? I was always under the impression that you shouldn’t appear too keen!
It’s about getting the balance right. If you dote on every word he says, and come across like you have no identity of your own, then he’s very likely to be put off. If you come across as confident, intelligent, interesting and witty in your own right, then if he fancies you he’ll be paying you enough attention even if he’s not great with words.
Most of us men are crap at taking a compliment, be glad he said something back. I’ve been known to feel a bit on the spot when girls have complimented me before (it has happened, maybe only once or twice ever, but it has happened!) and came up with the response of… Wait for it… This is a good one… “Thanks” 😕
When things are right, these things normally just flow and you don’t really have to ask one another anything. You sure he’s definitely interested in that way? He may well be, but may just be the world’s most shy person. I’m terrible at knowing when to compliment a girl myself, as I may well be sat across the table from her, fancying the pants off her, hoping that something is going to happen sooner or later, but don’t know what to say to her myself without sounding either too full on or creepy, or just not interested in the slightest…
Find a low pressure situation to maybe slip a question in perhaps, one where he’s not concentrating solely on you but on doing something else as well (not bike riding if he rides bikes already)…
