Question about guy I'm seeing

Shannon
I've been seeing a guy for about a month or so on and off and he's been flirting with me a lot (saying I look stunning, winking face in texts etc). He's a gentleman too! He pays for everything even when I object and offer to pay my part of the tab. We also went to his fraternity formal as a date and we can keep conversation for hours! He's a really great guy.
The only problem is I'm not sure if I romantically like him yet. I like spending time with him and enjoy his company, but I'm not sure if I'm at he point where I can really be into him. It usually takes me a long, long time to like someone like that.
Do you ladies have any suggestions for me?? I don't want to lead him on but am not sure if this could turn into something more....
